MAX8791BGTA+

Overview

The MAX8791BGTA+ is a single-phase, synchronous MOSFET gate driver manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 4.2V to 5.5V and features non-inverting input logic. The device provides peak output currents of 2.2A source and 2.7A sink. Typical rise and fall times are 10ns and 8ns respectively. It is housed in an 8-TQFN (3x3) package with exposed pad and supports a junction temperature range from -40°C to +150°C.

Feature Summary

• Designed for single-phase synchronous MOSFET driving applications
• Features non-inverting logic interface for straightforward control
• Capable of high-speed switching with low propagation delays

Applications

• DC-DC converter power stages
• Synchronous rectification circuits
• Motor drive systems

Procurement Notes

Verify component authenticity through authorized channels as the part status is listed as obsolete. Confirm final assembly marks and lot codes against manufacturer records. Ensure storage conditions meet moisture sensitivity level requirements prior to reflow soldering. Check for any specific handling instructions related to the exposed thermal pad.

Selection Notes

Select this driver when a compact solution for single-phase synchronous rectification is required. The wide operating temperature range suits industrial environments. Ensure the control signal polarity matches the non-inverting configuration. Verify that the load capacitance does not exceed the driver's current capability limits during switching transitions.

Part Context

This component belongs to the MAX8791 series of gate drivers. It is distinct from linear regulators like the MAX6791 or ADCs like the MAX191. The device integrates high-side and low-side drivers on a single chip to simplify PCB layout and reduce component count in power conversion designs.
