Product details
Overview
MAX5063BASA+T from Maxim Integrated is a 125V, 2A high-speed half-bridge MOSFET driver with noninverting high-side and inverting low-side outputs, TTL logic inputs, 35ns typical propagation delay, ±8ns matched delay between drivers, and integrated bootstrap diode - designed for telecom half-bridge power supplies operating up to 1MHz.
For engineers reviewing the MAX5063BASA+T datasheet, MAX5063BASA+T pinout, MAX5063BASA+T application, or MAX5063BASA+T equivalent, key selection criteria include its 125V HS voltage rating, 2A peak source/sink drive strength, -40°C to +125°C automotive temperature range, and 8-pin SO package compatibility with standard PCB footprints.
Technical Context
The MAX5063BASA+T implements independent high- and low-side gate drivers using BiCMOS process technology, enabling 35ns typical propagation delay with ≤8ns matching across temperature. Its TTL-compatible logic inputs (VIH = 2V, VIL = 1.4V) operate independently of VDD and tolerate up to 15V transients.
It integrates a 0.91V forward-drop internal bootstrap diode between VDD and BST, eliminating external diode requirements. The device features undervoltage lockout on both VDD (6.5–8.0V) and BST-to-HS (6.0–7.8V), with 0.5V hysteresis, and supports stable operation driving 100nC gate charges at high frequencies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| HS Voltage Rating | 125V max - enables direct use in 100V transient telecom systems with safety margin |
| Peak Output Current | 2A source/sink - drives high-gate-charge MOSFETs (e.g., 100nC) without external buffers |
| Propagation Delay | 35ns typical - supports >1MHz switching in telecom and industrial DC/DC converters |
| Delay Matching | ≤8ns max - minimizes shoot-through risk in half-bridge topologies without external dead-time control |
| VDD Range | 8.0V to 12.6V - compatible with standard 12V bias rails and tolerant of supply sag |
| Logic Input Type | TTL - accepts 1.4V/2V thresholds, decoupled from VDD, enabling mixed-voltage system interfacing |
| UVLO Thresholds | VDD: 6.5–8.0V; BST-to-HS: 6.0–7.8V - prevents erratic switching during brownout or bootstrap charging failure |
Pinout & Package
MAX5063BASA+T is housed in an 8-pin SO (Small Outline) package (JEDEC MS-012AA, pkg code S8-5), thermally optimized for surface-mount assembly and compatible with industry-standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 BST | Boost capacitor connection | Connects to flying capacitor (0.1µF ceramic) between BST and HS; powers high-side driver via internal diode |
| 2 DH | High-side gate driver output | Drives high-side N-MOSFET gate; rated for 125V HS potential and 2A peak current |
| 3 HS | High-side source reference | Serves as return path for high-side driver and source node of external high-side MOSFET |
| 4 GND | Ground reference | Analog ground for logic inputs (IN_H, IN_L); must be tied to system ground plane |
| 5 IN_H | High-side noninverting logic input | TTL-compatible input (VIH ≥ 2V); controls DH output directly; active-high |
| 6 IN_L | Low-side inverting logic input | TTL-compatible input (VIH ≥ 2V); controls DL output inversely; active-high input yields low DL output |
| 7 DL | Low-side gate driver output | Drives low-side N-MOSFET gate; referenced to GND; 2A peak sink/source capability |
| 8 VDD | Power supply input | 8–12.6V supply; bypass with 0.1µF + 1µF ceramics to GND; powers both drivers and logic |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bootstrap diode | 0.91V forward drop eliminates need for external Schottky diode, reducing BOM count and layout area |
| Matched propagation delay | ≤8ns max mismatch between DH and DL ensures precise timing alignment critical for shoot-through prevention |
| TTL logic inputs | 1.4V/2V thresholds with 0.25V hysteresis enable robust noise immunity and compatibility with standard PWM controllers |
| 125V high-side rating | Supports direct integration into 48V telecom systems with 100V transient compliance per GR-1089-CORE |
| Automotive temperature range | -40°C to +125°C operation allows deployment in under-hood or base station power modules without derating |

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 |
|---|---|---|---|
| MAX5062BASA+T | CMOS (VDD/2) logic inputs instead of TTL; identical pinout, timing, and drive specs | Requires VDD-referenced controller outputs; less tolerant of logic voltage mismatches than TTL version | Select when controller uses CMOS-level signaling and VDD is stable; otherwise MAX5063BASA+T preferred for broader logic compatibility |
| UCC27211D | 120V HS rating (vs. 125V), 4A peak drive (vs. 2A), no integrated bootstrap diode, 10-pin WSON package | Requires external bootstrap diode and tighter layout for high-frequency EMI control; higher drive supports faster slew rates | Choose for higher-current gate drive needs or when external bootstrap diode is already present; not drop-in due to different pinout and missing diode |
Compared with MAX5062BASA+T and UCC27211D, MAX5063BASA+T offers optimal balance of TTL logic flexibility, integrated bootstrap diode, and 125V rating - making it ideal for telecom and industrial half-bridge designs where layout simplicity and transient margin are prioritized over maximum peak current.

FAQ
What is the logic input type for MAX5063BASA+T?
MAX5063BASA+T features TTL-compatible logic inputs with VIH ≥ 2.0V (min) and VIL ≤ 1.4V (max), providing robust noise immunity and compatibility with standard PWM controllers. Unlike CMOS-input variants, its logic thresholds are fixed and independent of VDD, enabling reliable interfacing across varying supply voltages - a key advantage in multi-rail systems where MAX5063BASA+T operates.
Does MAX5063BASA+T include an integrated bootstrap diode?
Yes, MAX5063BASA+T integrates a low-forward-voltage (0.91V typical) bootstrap diode between VDD and BST pins. This eliminates the need for an external discrete diode in most applications, reducing component count, board space, and potential failure points - a distinguishing feature confirmed in the device's Absolute Maximum Ratings and Detailed Description sections of the official datasheet for MAX5063BASA+T.
What is the maximum high-side voltage rating of MAX5063BASA+T?
MAX5063BASA+T supports a maximum high-side voltage (VHS) of 125V, verified in its Absolute Maximum Ratings table. This provides 25V margin above the 100V transient requirement defined in telecom standards like GR-1089-CORE, ensuring reliable operation in 48V input systems subjected to lightning-induced surges or load-dump events - a critical specification for MAX5063BASA+T in base station power supplies.
What package does MAX5063BASA+T use?
MAX5063BASA+T is supplied in an 8-pin SO (Small Outline) package per JEDEC MS-012AA, with package code S8-5. It is lead-free, RoHS-compliant, and designed for standard surface-mount assembly and reflow processes - identical in footprint and pinout to industry-standard 8-pin SO drivers, enabling drop-in replacement in existing layouts without redesign for MAX5063BASA+T.
What is the propagation delay matching specification for MAX5063BASA+T?
MAX5063BASA+T guarantees ≤8ns maximum propagation delay mismatch between its high-side (DH) and low-side (DL) drivers across -40°C to +125°C, as specified in the Electrical Characteristics table under "Delay Matching Between Driver-Low and Driver-High". This tight matching minimizes shoot-through risk in half-bridge topologies and reduces dependency on external dead-time circuits - a core performance attribute of MAX5063BASA+T.
