A6861 - Automotive 3-Phase Isolator MOSFET Driver

General Description

The A6861 is an N-channel power MOSFET driver capable of controlling MOSFETs connected as a three-phase solid-state relay in phase-isolation applications.

The A6861 is intended for automotive systems that must meet ASIL requirements.

Key Features

  • Three floating N-channel MOSFET drives.
  • Maintains VGS with 100 kΩ gate-source resistors.
  • Integrated charge pump controller.
  • 4.5 to 50 V supply voltage operating range.
  • Independent TTL input for each phase.
  • 150°C ambient (165°C junction) continuous.
  • A2-SIL™ product.
  • device features for safety-critical systems.
