AOZ59141DI

Overview

The AOZ59141DI is a half-bridge gate driver IC manufactured by Alpha & Omega Semiconductor Inc. It operates with a supply voltage range of 4.5V to 5.5V and supports load voltages up to 25V. The device features independent channels with non-inverting logic, providing peak source and sink output currents of 2A and 4A respectively. Typical rise and fall times are 8ns. It is housed in an 8-DFN-EP (2x2) package and functions within an operating temperature range of -40°C to 125°C.

Feature Summary

• Non-inverting half-bridge configuration for precise control
• High peak output current capability of 4A sink
• Compact 8-DFN-EP package design
• Independent channel operation

Applications

• Synchronous buck converters
• DC-DC converter stages
• Power management modules

Procurement Notes

Verify the specific suffix 'DI' against official Alpha & Omega Semiconductor datasheets to confirm pinout and thermal pad specifications. Ensure compatibility with system voltage requirements of 4.5V to 5.5V. Confirm that the 8-DFN-EP package footprint matches the PCB layout constraints. Check for any RoHS or REACH compliance documentation required for the target market.

Selection Notes

Select this component when a compact half-bridge driver with high sink current is required for low-voltage applications. The 4.5V to 5.5V supply range suits standard logic levels. Consider the 8-DFN-EP package for space-constrained designs requiring efficient thermal dissipation through the exposed pad. Verify that the 8ns switching speed meets the frequency requirements of the target power stage.

Part Context

This part belongs to the gate driver category within Alpha & Omega Semiconductor's portfolio. It is designed for driving external MOSFETs in power conversion circuits. The manufacturer specializes in discrete semiconductors and PMICs. This specific model targets applications needing reliable half-bridge control in a small form factor.

Replacement Considerations

Check for direct substitutes from Alpha & Omega with identical pinouts and electrical characteristics. Verify if other manufacturers offer compatible half-bridge drivers with similar 4A sink current and 8-DFN-EP packaging. Ensure replacement parts support the same 4.5V to 5.5V supply range and non-inverting logic.
