H-bridge Pre-driver IC: TB9057FG

This figure shows a inside of TB9057FG H-bridge Motor Pre-driver IC.

H-bridge pre-driver IC designed for high-current applications such as electric power steering (EPS)

  • H-bridge pre-driver (that requires an external FET)
  • Built-in charge pump (with a VB of +7 V or greater)
  • Low-side pre-driver for low-voltage drive (a charge pump is used to boost a supply voltage)
  • Built-in circuit for motor rotation direction detection
  • High-speed pre-driver
  • Built-in high-speed and high-accuracy motor current sense circuit
  • Duplicate power and ground terminals as a provision for functional safety
  • Various detection circuits (undervoltage detection, FET short-circuit detection, thermal shutdown)
  • Supply voltage: 40 Vpeak (load dump)
  • Operating voltage: 5 to 21 V
  • PWM frequency: 20 kHz
  • Operating temperature: Ta = -40 to +125 ℃
  • Package: LQFP48
