Analog Devices Inc./Maxim Integrated MAX5062AASA+

Overview

MAX5062AASA+ from Maxim Integrated is a 125V, 2A high-speed half-bridge MOSFET driver with noninverting high-side and low-side outputs, CMOS (VDD/2) logic inputs, and integrated bootstrap diode. It delivers matched 35ns typical propagation delay (≤8ns max mismatch), 2A peak source/sink current, and operates from 8V–12.6V VDD across –40°C to +125°C - enabling robust telecom power supplies and active-clamp forward converters.

For engineers reviewing the MAX5062AASA+ datasheet, MAX5062AASA+ pinout, MAX5062AASA+ application, or MAX5062AASA+ equivalent, this device is selected for high-frequency half-bridge gate driving where propagation delay matching, 125V HS voltage tolerance, and thermally enhanced SO-8 packaging are critical in telecom and industrial DC/DC designs.

Technical Context

The MAX5062AASA+ implements independent high-side and low-side drivers using BiCMOS output stages with 2.5Ω typical R_ON (sourcing/sinking), enabling fast switching into 100nC gate loads. Its internal bootstrap diode (0.91V V_F, 40ns t_R/t_F) eliminates external diode requirements while supporting bootstrap capacitor charging during low-side conduction.

It features dual undervoltage lockout (UVLO) thresholds - 6.5V–8.0V for VDD (referred to GND) and 6.0V–7.8V for BST (referred to HS) - with 0.5V hysteresis, ensuring safe startup and fault recovery in high-voltage transient environments per telecom standards.

FAQ

What is the maximum high-side voltage rating for MAX5062AASA+?

The MAX5062AASA+ supports a maximum high-side voltage (V_HS) of 125V, providing ≥25V margin above the 100V transient requirement defined in telecom standards such as GR-1089. This rating is absolute - not dependent on duty cycle or switching frequency - and applies across the full –40°C to +125°C operating temperature range. The device maintains safe operation even under fast dV/dt events up to 50V/ns.

Does MAX5062AASA+ include an integrated bootstrap diode?

Yes, MAX5062AASA+ integrates a bootstrap diode between VDD and BST pins with a typical forward voltage drop of 0.91V at 100mA and 40ns turn-on/turn-off time. This eliminates the need for an external Schottky diode in most applications, reducing component count and board space. The diode is rated for continuous 100mA and supports reliable bootstrap capacitor charging during DL conduction in half-bridge and active-clamp topologies.

What logic input type does MAX5062AASA+ use, and what are its voltage tolerances?

MAX5062AASA+ uses CMOS (VDD/2) logic inputs with hysteresis of 1.6V. Input pins (IN_H+, IN_L+) accept logic signals referenced to AGND, with VIH = 0.67×VDD (min) and VIL = 0.4×VDD (max). All inputs tolerate up to 15V absolute maximum regardless of VDD voltage - enabling interoperability with controllers operating at different supply rails. Input leakage is ±1µA, and input capacitance is 2.5pF.

Is MAX5062AASA+ pin-compatible with any legacy drivers?

Yes, MAX5062AASA+ is pin-compatible with HIP2100IB and HIP2101IB in the 8-pin SO package. It matches pin-for-pin function, electrical behavior, and thermal profile - allowing direct replacement without PCB modification. This compatibility extends to layout, bypassing, and bootstrap capacitor placement, making it ideal for upgrading aging telecom power designs while maintaining qualification status.

What is the guaranteed propagation delay matching between DH and DL outputs in MAX5062AASA+?

MAX5062AASA+ guarantees ≤8ns maximum propagation delay mismatch (t_MATCH2) between DH and DL outputs over –40°C to +125°C and full VDD range (8V–12.6V). This specification covers both turn-on and turn-off paths and is measured under identical load conditions (CL = 1000pF). The typical matching is 3ns, enabling precise dead-time control without external calibration or trimming circuits.
