Overview
The MAX8791AGTA+T is a half-bridge gate driver IC 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 sink and 2.7A source, with typical rise and fall times of 10ns and 8ns respectively. Designed for synchronous MOSFETs, it utilizes an 8-TQFN (3x3) surface-mount package and supports junction temperatures from -40°C to 150°C.
Feature Summary
- Provides high-current drive capability for synchronous N-channel MOSFETs in half-bridge configurations.
- Features fast switching performance with low propagation delays for efficient power conversion.
- Operates reliably across an extended industrial temperature range up to 150°C junction temperature.
Applications
- DC-DC converter circuits requiring synchronous rectification
- Power management modules for computing and server applications
- Industrial motor control systems utilizing half-bridge topologies
Procurement Notes
Verify component authenticity through authorized channels due to discontinuation status. Confirm RoHS3 compliance and check for specific lot traceability requirements. Ensure storage conditions meet moisture sensitivity level standards prior to assembly. Validate that the TQFN footprint matches design specifications to prevent soldering defects during placement.
Selection Notes
Select this component when designing systems requiring robust half-bridge driving with high thermal tolerance. Consider the 8-TQFN package constraints for PCB layout and thermal dissipation needs. Evaluate the 4.2V to 5.5V supply range against available system rails. Assess the 2.2A/2.7A current drive against target MOSFET gate charge requirements for optimal switching efficiency.
Part Context
The MAX8791 series belongs to Maxim Integrated's portfolio of specialized power management integrated circuits. This specific model focuses on gate driving applications where compact size and high reliability are critical. The AG suffix typically denotes automotive-grade qualification or specific temperature variants within the broader MAX8791 family line.
Replacement Considerations
