Analog Devices Inc./Maxim Integrated MAX5062DASA+

Overview

MAX5062DASA+ from Maxim Integrated is a 125V, 2A high-speed half-bridge MOSFET driver with noninverting high-side and inverting low-side outputs, CMOS (VDD/2) logic inputs, and matched 35ns typical propagation delay (≤8ns max mismatch). It operates from 8V–12.6V VDD, supports telecom power supplies up to 100V transient input, and integrates a reliable on-chip bootstrap diode between VDD and BST.

For engineers reviewing the MAX5062DASA+ datasheet, MAX5062DASA+ pinout, MAX5062DASA+ application, or MAX5062DASA+ equivalent, this page delivers verified electrical specs, thermal package details, real-world timing behavior, and validated alternative options for high-frequency half-bridge gate driving in telecom and industrial power converters.

Technical Context

The MAX5062DASA+ implements independent high- and low-side drivers using BiCMOS output stages with 2.5Ω typical R_ON (sourcing/sinking), enabling 2A peak current into 10nF loads. Its level-shifted architecture achieves 35ns typical propagation delay with ≤8ns guaranteed matching between DH and DL paths - critical for shoot-through prevention in synchronous topologies.

It features dual UVLO thresholds (6.5–8.0V for VDD, 6.0–7.8V for BST-to-HS), internal 0.91–1.11V bootstrap diode, and thermally enhanced 8-pin SO-EP package with exposed paddle tied to AGND. Logic inputs tolerate up to 15V regardless of VDD and exhibit 2.5pF capacitance and 1MΩ input resistance.

Key Specifications

Pinout & Package

MAX5062DASA+ uses an 8-pin SOIC with exposed paddle (S8E-14), where the EP pad is internally connected to AGND and must be externally soldered to a large ground plane for optimal thermal performance.

Equivalent & Alternatives

The following parts are listed as comparable options for similar half-bridge gate driver applications.

Compared with MAX5062BASA+, MAX5062DASA+ delivers 3.3× higher thermal power handling due to its exposed paddle; versus UCC27211D, it trades off peak current for integrated bootstrap functionality and CMOS input flexibility - making it optimal for space-constrained telecom modules requiring robust startup and minimal BOM count.

FAQ

What is the maximum operating voltage on the HS pin of the MAX5062DASA+?

The MAX5062DASA+ supports a maximum HS voltage of 125V, providing 25V margin above the 100V transient requirement specified in telecom standards. This rating is absolute and applies across the full -40°C to +125°C temperature range, with dV/dt immunity up to 50V/ns. Exceeding 125V risks permanent damage per Absolute Maximum Ratings.

Does the MAX5062DASA+ include an internal bootstrap diode?

Yes, the MAX5062DASA+ integrates a reliable on-chip bootstrap diode between VDD and BST pins. It has a typical forward voltage drop of 0.91–1.11V at 100mA and 10ns turn-on/turn-off time. This eliminates the need for an external Schottky diode in most applications, reducing BOM count and PCB area - though an external diode may be added for lower forward drop in high-efficiency designs.

What logic levels are compatible with the MAX5062DASA+ inputs?

The MAX5062DASA+ uses CMOS (VDD/2) logic inputs with 1.6V hysteresis, supporting VIH = 0.67×VDD (min) and VIL = 0.4×VDD (max). Inputs tolerate up to 15V regardless of VDD level, enabling direct interface with 3.3V, 5V, or 12V controllers. The IN_H pin is noninverting and pulled down internally; IN_L is inverting and pulled up - both require explicit logic states during power-up to avoid undefined outputs.

How does the MAX5062DASA+ handle undervoltage lockout (UVLO)?

The MAX5062DASA+ implements dual independent UVLO circuits: VDD UVLO triggers at 6.5–8.0V (rising) with 0.5V hysteresis, pulling DL low; BST-to-HS UVLO activates at 6.0–7.8V (rising), pulling DH low. This ensures safe shutdown during bootstrap capacitor undercharge or main supply brownout - critical for preventing shoot-through in half-bridge configurations. Both thresholds are guaranteed over temperature.

What package type does the MAX5062DASA+ use, and how should the exposed paddle be handled?

The MAX5062DASA+ uses an 8-pin SOIC with exposed paddle (package code S8E-14). The EP pad is internally connected to AGND and must be soldered to a large copper ground plane on the PCB to achieve the rated 19.2mW/°C thermal derating above +70°C. Failure to connect the paddle degrades thermal performance by >70%, risking junction overheating above 1W dissipation.
