Product details
Overview
MAX5064BATC+ from Maxim Integrated is a 125V, 2A high-speed half-bridge MOSFET driver with independently controlled high- and low-side outputs, 35ns typical propagation delay (±3ns matching), programmable break-before-make timing (16–95ns), and integrated bootstrap diode - designed for telecom half-bridge power supplies operating up to 1MHz with 100nC gate charge.
For engineers reviewing the MAX5064BATC+ datasheet, MAX5064BATC+ pinout, MAX5064BATC+ application, or MAX5064BATC+ equivalent, key selection criteria include matched propagation delay tolerance, BBM programmability via external resistor, thermal performance in 12-pin QFN, and TTL logic input compatibility with 15V absolute max rating independent of VDD.
Technical Context
The MAX5064BATC+ implements dual independent gate drivers using BiCMOS process technology, enabling 2A peak source/sink current with <3.3Ω output resistance at +25°C. Its level-shifted high-side driver operates up to 125V referenced to HS, with internal bootstrap diode (0.91V VF) eliminating external diode requirement.
Unlike MAX5062/MAX5063 variants, MAX5064BATC+ features two logic inputs per channel (IN_H+/IN_H−, IN_L+/IN_L−), supporting configurable inverting/noninverting operation and active-high/active-low shutdown. It includes dedicated AGND/PGND separation, BBM programming pin (BBM), and guaranteed 8ns max propagation delay matching between DH and DL outputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Input Voltage | 125V on HS pin - supports telecom transients beyond 100V standard with safety margin. |
| Peak Output Current | 2A source/sink - drives high-gate-charge MOSFETs (e.g., 100nC) at up to 1MHz switching frequency. |
| Propagation Delay | 35ns typical (IN to DH/DL) - enables precise timing control in high-frequency converters. |
| Delay Matching | ≤8ns max mismatch between DH and DL - prevents shoot-through in synchronous topologies. |
| BBM Timing Range | 16ns to 95ns via RBBM (10kΩ–100kΩ) - eliminates external dead-time circuitry. |
| Logic Input Type | TTL-compatible (MAX5064B variant) - accepts 1.65V–2V VIH, 0.8V VIL, independent of VDD voltage. |
| Supply Voltage Range | 8.0V to 12.6V on VDD - ensures stable operation across industrial input rails. |
Pinout & Package
MAX5064BATC+ is housed in 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 PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Power input | Bypass to PGND with 0.1µF + 1µF ceramic capacitors; powers both drivers and logic. |
| BST | Bootstrap supply node | Connects to flying capacitor (0.1µF) between BST and HS; internal diode charges capacitor during DL on-time. |
| DH | High-side gate drive output | Sinks/sources 2A to drive N-channel MOSFET gate; referenced to HS potential. |
| HS | High-side source return | Return path for high-side driver; must be connected to MOSFET source node. |
| IN_H | High-side noninverting logic input | TTL-compatible; controls DH output directly; 15V absolute max rating decouples from VDD. |
| IN_L | Low-side noninverting logic input | TTL-compatible; controls DL output directly; hysteresis prevents noise-induced switching. |
| GND | Analog ground reference | Return for logic inputs and internal circuitry; separate from PGND to reduce noise coupling. |
| DL | Low-side gate drive output | Sinks/sources 2A to drive N-channel MOSFET gate; referenced to PGND. |
| PGND | Power ground return | Return path for DL output and high-switching-current paths; must be low-inductance plane. |
| BBM | Break-before-make timing adjust | Connect external resistor (10kΩ–100kΩ) to AGND to set dead time; bypass with ≥1nF capacitor. |
| EP | Exposed thermal pad | Internally tied to AGND; requires soldered connection to large copper pour for thermal management. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bootstrap diode | Eliminates external Schottky diode; 0.91V forward drop reduces conduction loss and board area. |
| Programmable dead time | 16–95ns BBM via single external resistor - replaces discrete RC delay networks and simplifies layout. |
| Independent logic inputs | Two per channel (IN_H+/IN_H−, IN_L+/IN_L−) enables flexible PWM control, fault shutdown, or polarity inversion without external gates. |
| AGND/PGND separation | Reduces noise coupling between sensitive logic and high-current switching paths - critical for EMI-sensitive telecom designs. |
| 15V logic input tolerance | Allows interface with higher-voltage controllers (e.g., 12V CMOS) while powered from 8–12.6V VDD - improves system-level interoperability. |

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+ | CMOS (VDD/2) logic inputs instead of TTL; identical pinout, BBM, and thermal specs. | Suitable where controller outputs match VDD/2 thresholds (e.g., 3.3V MCU with 1.65V VIH); not compatible with 5V TTL sources. | Select MAX5064AATC+ when interfacing with CMOS logic; MAX5064BATC+ for TTL or mixed-voltage systems. |
| UCC27211DRCR | 120V max HS, 4A peak current, no integrated bootstrap diode, no BBM programming pin. | Requires external bootstrap diode and dead-time circuitry; better suited for cost-sensitive, lower-power (<500kHz) applications. | Choose UCC27211DRCR only if higher peak current is required and board space permits external components. |
Compared with MAX5064AATC+, MAX5064BATC+ offers direct TTL compatibility and wider input voltage tolerance; versus UCC27211DRCR, it delivers integrated BBM and bootstrap diode - reducing BOM count and layout complexity in telecom-grade power supplies.

FAQ
What is the maximum allowable voltage on the HS pin of the MAX5064BATC+?
The MAX5064BATC+ supports up to +125V on the HS pin relative to GND. This rating provides headroom above the 100V transient requirement defined in telecom standards like GR-1089. Operation beyond this limit risks permanent damage, and the device includes dV/dt immunity up to 50V/ns on HS to suppress false triggering during fast transients.
Does the MAX5064BATC+ require an external bootstrap diode?
No, the MAX5064BATC+ integrates a reliable on-chip bootstrap diode between VDD and BST with 0.91V typical forward voltage. This eliminates the need for an external discrete diode, reducing component count and PCB area. An external Schottky diode may be added only if lower forward drop is required to improve efficiency at very high switching frequencies.
How is break-before-make timing programmed on the MAX5064BATC+?
Break-before-make timing on the MAX5064BATC+ is set by connecting a resistor (RBBM) from the BBM pin to AGND. Values from 10kΩ to 100kΩ yield dead times from 16ns to 95ns respectively. The BBM pin must be bypassed with ≥1nF capacitor to AGND to suppress ground bounce effects. Leaving BBM open disables BBM, resulting in ~1ns intrinsic dead time.
What logic levels does the MAX5064BATC+ accept on its IN_H and IN_L pins?
The MAX5064BATC+ (B version) accepts TTL-compatible logic levels: VIH = 1.65V–2V, VIL = 0.8V max, with 0.25V hysteresis. Inputs tolerate up to 15V regardless of VDD, enabling direct interface with 3.3V, 5V, or 12V controllers. Input capacitance is only 2.5pF, minimizing loading on driving circuits.
Can the MAX5064BATC+ drive both high- and low-side N-channel MOSFETs in a synchronous buck converter?
Yes, the MAX5064BATC+ is specifically designed for synchronous buck and half-bridge topologies. Its high-side driver uses level-shifting architecture to control an N-channel MOSFET referenced to HS, while the low-side driver operates referenced to PGND. The programmable BBM function prevents shoot-through during transitions, and the 2A peak current supports fast switching of high-gate-charge devices.
