Product details
Overview
MAX5064BATC+T from Maxim Integrated is a 125V, 2A high-speed half-bridge MOSFET driver IC with independently controlled high-side and low-side outputs, 35ns typical propagation delay (matched within 8ns), programmable break-before-make timing (16–95ns), and integrated bootstrap diode - designed for telecom power converters operating up to 1MHz with 100nC gate charge loads.
For engineers reviewing the MAX5064BATC+T datasheet, MAX5064BATC+T pinout, MAX5064BATC+T application, or MAX5064BATC+T equivalent, this page delivers verified electrical specs, thermal package details, real-world dead-time programming guidance, and validated alternatives for high-voltage half-bridge gate driving in telecom and industrial power supplies.
Technical Context
The MAX5064BATC+T implements dual independent BiCMOS gate drivers with TTL logic inputs, separate AGND/PGND grounds, and a dedicated BBM adjustment pin (BBM) that sets dead time via external resistor (10kΩ–100kΩ). Its internal bootstrap diode (VF = 0.91V typ) eliminates discrete diode requirements while supporting 125V HS operation.
It features matched propagation delays between DH and DL outputs (≤8ns max mismatch), 2A peak source/sink current per channel, and UVLO thresholds at 6.5–8.0V (VDD) and 6.0–7.8V (BST-to-HS), all guaranteed over –40°C to +125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VHS Max | 125V - supports telecom transient margin above 100V input requirement |
| Peak Output Current | 2A source/sink - drives high-gate-charge MOSFETs (e.g., 100nC) at up to 1MHz |
| Propagation Delay | 35ns typical - enables high-frequency switching with tight timing control |
| Delay Matching | ≤8ns max - prevents shoot-through by minimizing DH/DL timing skew |
| BBM Time Range | 16–95ns - externally programmed via RBBM (10kΩ–100kΩ) for safe half-bridge commutation |
| VDD Range | 8.0–12.6V - powers logic and output stages with UVLO hysteresis of 0.5V |
| Input Logic Type | TTL - accepts 1.65–2.0V VIH and 0.8–1.4V VIL, independent of VDD |
Pinout & Package
MAX5064BATC+T uses a thermally enhanced 12-pin (4mm × 4mm) thin QFN package with exposed pad (EP) internally connected to AGND. The package supports 1.95W power dissipation at +70°C and enables compact, high-power-density layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Power Input | Bypassed to PGND with 0.1µF + 1µF ceramics; supplies both logic and driver stages |
| BST | Bootstrap Capacitor Node | Connects to HS via 0.1µF ceramic; internal diode charges BST from VDD during low-side conduction |
| DH | High-Side Gate Driver Output | Drives N-channel MOSFET gate referenced to HS; sinks 2A into gate capacitance |
| HS | High-Side Source Return | Common node for high-side MOSFET source and DH return path; withstands up to 125V |
| IN_H | High-Side Noninverting Logic Input | TTL-compatible; controls DH directly; VIH ≥ 2.0V, VIL ≤ 0.8V |
| IN_L | Low-Side Noninverting Logic Input | TTL-compatible; controls DL directly; same voltage thresholds as IN_H |
| GND | Analog Ground Reference | Return for IN_H/IN_L inputs; isolated from PGND to reduce noise coupling |
| DL | Low-Side Gate Driver Output | Drives N-channel MOSFET gate referenced to PGND; sources/sinks 2A |
| PGND | Power Ground | Return path for DL output and high-switching currents; must be low-inductance plane |
| BBM | Break-Before-Make Timing Input | Accepts resistor to AGND (10kΩ–100kΩ) to set tBBM = 16–95ns; bypass with ≥1nF capacitor |
| EP | Exposed Thermal Pad | Internally tied to AGND; requires soldered connection to large copper area for thermal management |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Bootstrap Diode | VF = 0.91V typ - eliminates external Schottky diode, reducing BOM count and layout area |
| Programmable Dead Time | tBBM = 16–95ns - prevents shoot-through in half-bridge/synchronous buck topologies without external circuitry |
| Matched Propagation Delays | ≤8ns max mismatch between DH and DL - ensures precise timing alignment under temperature and supply variation |

Applications
| Telecom Half-Bridge Power Supplies | Two-Switch Forward Converters |
|---|---|
Use Scenario: 48V input telecom rectifier supplying 12V/50A output using half-bridge topology with synchronous rectification. IC Role / Device Role / Timing Role: Drives high-side and low-side 100nC MOSFETs at 500kHz with programmable dead time to prevent shoot-through during 100V transients. Use Value: 125V HS rating provides 25V margin over GR-1089-CORE 100V surge spec; integrated bootstrap diode reduces component count by one. | Use Scenario: Isolated 380V DC bus converter for server PSUs, using two active switches in forward configuration with 300kHz switching. IC Role / Device Role / Timing Role: Controls complementary gate drive for primary-side switches; BBM disabled (BBM open) since both switches operate simultaneously. Use Value: Dual independent drivers enable precise timing control; 2A drive strength ensures fast 100nC MOSFET turn-on/turn-off at full load. |
| Full-Bridge Converters | Active-Clamp Forward Converters |
Use Scenario: 380V input full-bridge DC/DC for industrial motor drives, delivering 48V/100A with ZVS optimization. IC Role / Device Role / Timing Role: One MAX5064BATC+T drives leg A (DH/AL); second drives leg B (DH/BL); each uses BBM to avoid cross-conduction. Use Value: Matched 35ns delays ensure symmetrical leg timing; 8ns max mismatch maintains ZVS window integrity across temperature. | Use Scenario: High-efficiency 400V input active-clamp forward converter for telecom base station RF power amplifiers. IC Role / Device Role / Timing Role: Drives main switch (low-side) and clamp switch (high-side) with independent timing control and adjustable dead time. Use Value: Programmable BBM allows fine-tuning of clamp switch timing relative to main switch, optimizing efficiency and reducing voltage spikes. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar half-bridge gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX5064AATC+T | CMOS (VDD/2) logic inputs instead of TTL; identical pinout, package, and BBM functionality | Suitable when controller outputs are CMOS-level (e.g., microcontroller GPIO), not TTL | Select MAX5064AATC+T for VDD/2 threshold compatibility; MAX5064BATC+T for standard 5V/3.3V TTL PWM signals |
| UCC27211DRCR | 120V HS rating, 4A peak drive, no integrated bootstrap diode, no BBM programming pin | Requires external bootstrap diode and dead-time generation circuitry; higher drive strength for ultra-low-Qg MOSFETs | Choose UCC27211DRCR only if 4A drive or 120V rating suffices and external BBM control is acceptable |
Compared with MAX5064AATC+T, MAX5064BATC+T offers native TTL compatibility without level-shifting, while versus UCC27211DRCR it trades higher peak current for integrated bootstrap and programmable dead time - critical for compact telecom PSU designs where layout space and reliability are constrained.

FAQ
What is the maximum switching frequency supported by the MAX5064BATC+T?
The MAX5064BATC+T supports up to 1MHz combined switching frequency when driving a total gate charge of 100nC, as confirmed in the Electrical Characteristics table and Typical Operating Characteristics (toc08). This capability is enabled by its 2A peak source/sink current, 35ns propagation delay, and thermally enhanced 12-pin QFN package rated for 1.95W dissipation at +70°C. Real-world operation depends on MOSFET gate charge, PCB layout, and thermal management - but 1MHz is the validated limit under specified conditions for MAX5064BATC+T.
Does the MAX5064BATC+T include an internal bootstrap diode?
Yes, the MAX5064BATC+T integrates a reliable on-chip bootstrap diode between VDD and BST, with a typical forward voltage drop of 0.91V at 100mA and 10ns turn-on/turn-off time. This eliminates the need for an external discrete diode in most designs, reducing component count and board area. The diode is explicitly documented in the "Internal Bootstrap Diode" section and Electrical Characteristics table (Vf parameter), and its function is confirmed in the Typical Operating Circuit and Applications Information. Use an external Schottky diode only if lower VF (<0.5V) is required for efficiency-critical applications.
How is break-before-make timing programmed on the MAX5064BATC+T?
Break-before-make timing on the MAX5064BATC+T is programmed by connecting a resistor (RBBM) from the BBM pin to AGND. Values from 10kΩ to 100kΩ yield tBBM from 16ns to 95ns, per the equation tBBM = 8ns × (1 + RBBM/10kΩ). A 1nF or smaller ceramic capacitor must bypass BBM to AGND to suppress ground bounce. This feature is exclusive to MAX5064 variants (not MAX5062/MAX5063) and is fully characterized in the Electrical Characteristics table and toc15/toc16 graphs. Leaving BBM unconnected disables BBM, resulting in ~1ns dead time.
What is the logic input type for the MAX5064BATC+T?
The MAX5064BATC+T features TTL-compatible logic inputs: IN_H and IN_L accept VIH ≥ 2.0V (min) and VIL ≤ 0.8V (max), with 0.25V hysteresis. These thresholds are independent of VDD voltage, allowing interface with 3.3V or 5V PWM controllers even when VDD = 12V. This is explicitly stated in the Selector Guide and Electrical Characteristics table under "LOGIC INPUT" for MAX5064B. It differs from the CMOS-input MAX5064AATC+T (VDD/2 thresholds), making MAX5064BATC+T ideal for standard TTL/CMOS logic families without level shifters.
What package and thermal specifications apply to the MAX5064BATC+T?
The MAX5064BATC+T uses a 12-pin thin QFN package (4mm × 4mm) with exposed thermal pad (EP), designated as "TQFN" in Maxim's ordering nomenclature and confirmed in the Ordering Information table. Its thermal performance is rated at 1.951W continuous power dissipation at +70°C (derating 24.4mW/°C above +70°C), per JEDEC 51 multilayer board standards. The EP is internally connected to AGND and must be soldered to a large copper ground plane for effective heat transfer - a requirement emphasized in the Pin Description and Applications Information sections.
