L9907 Datasheet Automotive Fet Driver

Manufacturer: STMicroelectronics

Overview: L9907 Automotive FET driver for 3 phase BLDC motor TQFP64 (exposed pad.

General Description

L9907 is a gate driver unit controlling 6 N-channel FETs for brushless DC motors in automotive applications.

Each pre-driver channel can be controlled independently allowing the implementation of all kinds of electric motor control strategy.

The base gate output current is set via an external resistor, while via SPI it is possible to select among 4 gate output current levels even when the application is running.

Key Features

  • AEC-Q100 qualified.
  • Supply voltage from 4.2 V to 54 V.
  • The device can withstand -7 V to 90 V at the FET high-side Driver pins.
  • Low standby current consumption.
  • Compatible with 3.3 V and 5 V Logic Level.
  • All logic pins withstand 35 V.
  • Boost regulator for full Rdson down to 6 V battery voltage.
  • 3 low-side + 3 high-side independent gate drivers.
  • PWM operation up to 20 kHz.
  • Adjustable gate driver controlled current up to 600 mA.
  • 2 programmable.
