A89103KEVSR-3

Overview

The A89103KEVSR-3 is an N-channel isolated power MOSFET driver designed for three-phase applications. It features five drivers and outputs, operating within a supply voltage range of 4.5 V to 85 V. The device utilizes a QFN-28 surface-mount package and supports an inverting configuration. Key timing parameters include a rise time of 1.2 µs and a fall time of 150 ns. It functions as an 80 V phase disconnect IC with a specified operating temperature range from -40 °C to 150 °C.

Feature Summary

Provides isolated gate driving capability for N-channel power MOSFETs in three-phase systems
Integrates five independent driver channels for comprehensive phase control
Supports wide input supply voltage ranges up to 85 V for robust operation

Applications

Three-phase motor drive systems
Inverter circuits requiring phase disconnect functionality
Industrial power conversion equipment

Procurement Notes

Verify the specific suffix 'EVS' against the manufacturer's official datasheet to confirm pinout compatibility and thermal pad specifications. Ensure the selected component matches the required inverting logic configuration and that the QFN-28 footprint aligns with the target PCB design constraints before finalizing procurement orders.

Selection Notes

Select this component when designing three-phase topologies requiring isolated gate driving for N-channel devices. Consider the 1.2 µs rise time and 150 ns fall time characteristics for switching speed requirements. Validate that the 85 V maximum supply rating accommodates the system's bus voltage and transient conditions effectively.
