Product details
Overview
MAX5063BASA+ 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 with 100nC gate charge.
For engineers reviewing the MAX5063BASA+ datasheet, MAX5063BASA+ pinout, MAX5063BASA+ application, or MAX5063BASA+ equivalent, this page delivers verified electrical specs, thermal package details, real-world timing behavior, and validated alternative options for high-voltage, high-frequency DC/DC converter design.
Technical Context
The MAX5063BASA+ implements independent high- and low-side drivers using BiCMOS process technology, enabling 2A peak source/sink current with 2.1–4.6Ω output resistance across temperature. Its TTL-compatible inputs (VIH = 2V, VIL = 1.4V) operate independently of VDD and tolerate up to 15V transients.
It features dual undervoltage lockout (UVLOVDD = 7.3V typ, UVLOBST = 6.9V typ), internal bootstrap diode (VF = 0.91V @ 100mA), and guaranteed 8ns max propagation delay matching - critical for minimizing shoot-through in telecom power converters where precise dead-time control is required without external BBM circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VHS Max | 125V - supports telecom input transients beyond 100V standard with safety margin. |
| IOUT Peak | 2A source/sink - drives high-gate-charge MOSFETs (e.g., 100nC) at up to 1MHz switching frequency. |
| tD_ON / tD_OFF | 35ns typical - enables fast switching in high-frequency telecom PSUs while maintaining timing predictability. |
| tMATCH2 | ≤8ns max - ensures tight synchronization between DH and DL edges to suppress cross-conduction. |
| VDD Range | 8.0V to 12.6V - compatible with standard 12V bias rails and provides stable operation across load/temperature. |
| CIN | 2.5pF - minimizes controller loading and preserves PWM signal integrity at high edge rates. |
| IDD Quiescent | 140µA max - reduces standby power in always-on telecom infrastructure equipment. |
Pinout & Package
MAX5063BASA+ is housed in an 8-pin SO (Small Outline) package with exposed pad (S8-5 code), thermally enhanced for automotive-grade operation (-40°C to +125°C). The package supports surface-mount reflow and provides low thermal resistance via the EP-to-AGND connection.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 BST | Bootstrap supply node | Connects internal diode anode to external 0.1µF BST–HS capacitor; eliminates need for discrete bootstrap diode. |
| 2 DH | High-side gate drive output | Drives N-channel MOSFET gate referenced to HS; capable of 2A sink/source into 10nF load. |
| 3 HS | High-side source return | Serves as floating ground reference for high-side driver and BST capacitor cathode. |
| 4 AGND | Analog ground reference | Return for IN_H/IN_L inputs and BBM resistor; must be separated from PGND in layout to avoid noise coupling. |
| 5 BBM | Break-before-make programming | Not used on MAX5063BASA+ - BBM function is exclusive to MAX5064 family; leave unconnected or bypass with ≥1nF to AGND. |
| 6 IN_H− | Inverting high-side logic input | TTL-compatible (VIL = 1.4V, VIH = 2V); internally pulled up to VDD; active-low control path for DH. |
| 7 IN_H+ | Noninverting high-side logic input | TTL-compatible; internally pulled down to AGND; active-high control path for DH. |
| 8 IN_L− | Inverting low-side logic input | TTL-compatible; internally pulled up to VDD; active-low control path for DL (matches MAX5063B/D configuration). |
| 9 IN_L+ | Noninverting low-side logic input | TTL-compatible; internally pulled down to AGND; active-high control path for DL. |
| 10 PGND | Power ground return | Return path for DL output and high-switching-current paths; must be tied to system power ground plane. |
| 11 DL | Low-side gate drive output | Drives N-channel MOSFET gate referenced to PGND; 2A sink/source capability with <0.2V dropout @ 100mA. |
| 12 VDD | Main supply input | 8–12.6V rail; bypass with 0.1µF + 1µF ceramics to PGND; UVLO triggers at 7.3V (rising). |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bootstrap diode | Eliminates external Schottky diode, reducing BOM count and PCB area while maintaining 0.91V forward drop. |
| TTL logic inputs | Supports direct interface with industry-standard PWM controllers without level-shifting; 15V absolute max rating protects against transients. |
| Matched propagation delay | ≤8ns max mismatch between DH and DL ensures synchronous turn-off and prevents shoot-through in hard-switched topologies. |
| Thermally enhanced SO package | S8-5 footprint with exposed pad dissipates up to 1.54W at +70°C ambient, enabling high-power density telecom PSU designs. |
| Automotive temperature range | -40°C to +125°C operation with 100% tested limits at +125°C - qualified for base station power modules and industrial converters. |

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+ | CMOS (VDD/2) logic inputs instead of TTL; identical pinout, timing, and drive strength. | Requires VDD-referenced controller outputs; less tolerant of 15V transients than MAX5063BASA+. | Select when interfacing with CMOS-based PWM ICs (e.g., MAX17595) and board-level voltage margins allow. |
| UCC27211D | 120V VHS, 4A peak drive, 17ns propagation delay, no integrated bootstrap diode, SO-8 package. | Lacks on-chip bootstrap diode - requires external Schottky; higher drive current suits larger gate charges but increases layout complexity. | Choose when >2A drive is needed or when using external bootstrap diodes for lower VF; verify UVLO thresholds match system requirements. |
Compared with MAX5062BASA+, MAX5063BASA+ offers superior transient immunity and controller compatibility due to TTL inputs, while UCC27211D trades integration for higher current and faster timing - making MAX5063BASA+ optimal for space-constrained telecom PSUs needing robustness and simplicity.

FAQ
What logic input type does MAX5063BASA+ use?
MAX5063BASA+ uses TTL-compatible logic inputs (VIH = 2V min, VIL = 1.4V max) with 0.25V hysteresis, allowing direct interface with standard PWM controllers like UC3844 or LM5113 without level shifting. This differs from the CMOS-input MAX5062BASA+, and the TTL specification is confirmed in the Ordering Information table and Electrical Characteristics section of the datasheet.
Does MAX5063BASA+ include an internal bootstrap diode?
Yes, MAX5063BASA+ integrates a reliable on-chip bootstrap diode between VDD and BST, with a typical forward voltage drop of 0.91V at 100mA. This eliminates the need for an external discrete diode, reducing component count and PCB area - a feature explicitly stated in the General Description and verified in the Internal Bootstrap Diode section of the datasheet.
What is the maximum high-side voltage rating for MAX5063BASA+?
MAX5063BASA+ supports up to 125V on the HS pin relative to GND, providing ample margin above the 100V transient requirement defined in telecom standards such as GR-1089. This rating is specified in Absolute Maximum Ratings and reinforced in the General Description and Detailed Description sections.
Is MAX5063BASA+ pin-compatible with HIP2100/HIP2101?
No, MAX5063BASA+ is not pin-compatible with HIP2100/HIP2101. The datasheet states pin compatibility only applies to MAX5062A/MAX5063A variants (CMOS-input versions), not the MAX5063BASA+. MAX5063BASA+ uses different input configurations (TTL with IN_H+/IN_H− and IN_L+/IN_L−) and lacks BBM functionality, resulting in distinct pin assignments and logic behavior.
What package type is used for MAX5063BASA+?
MAX5063BASA+ is supplied in an 8-pin SO (Small Outline) package with exposed thermal pad (package code S8-5), as confirmed in the Ordering Information table and Pin Configuration diagrams. It is not offered in QFN or SO-EP variants - those are reserved for MAX5062C/D, MAX5063C/D, and MAX5064 families.
