A89103 - Automotive Three-Phase and Battery Isolator MOSFET Driver

Datasheet Summary

Description

The A89103 is an N-channel power MOSFET driver capable of controlling five MOSFETs to provide motor-phase isolation and supply isolation in three-phase BLDC applications.

Features

  • Five floating N-channel MOSFET drives.
  • Maintains VGS with 100 kΩ gate-source resistors.
  • Integrated charge pump controller.
  • 4.5 to 85 V supply voltage operating range.
  • Supports source-to-source and drain-to-drain battery MOSFET isolation.
  • VCP and VGS undervoltage protection.
  • 150°C ambient (165°C junction) continuous.
  • Fully integrated diagnostics for safe motor phase and battery disconnect.
  • Extensive programmable dia.
