1-Channel Brushed DC Motor Driver IC: TB9051FTG

DC motor driver IC in a small package that is capable of controlling the throttle and other valves of a vehicle engine

The TB9051FTG is housed in a small QFN package (measuring 6 mm × 6 mm) and contributes to reducing the size of electronic control units (ECUs). The output stage has a low-on-resistance H-bridge that consists of P-channel and N-channel DMOS transistors. This eliminates the need for a charge pump and thus helps reduce noise and power consumption. To ensure functional safety, the supply voltage monitoring circuit performs initial diagnosis of each on-chip comparator. Applications of the TB9051FTG include opening and closing engine throttle and other valves; retracting electric door mirrors; and seat, rear door open/close and other applications that conduct current
exceeding 3 A.

  • 1-channel PWM H-bridge driver
  • Output current: 5 A
  • Low Ron DMOS: < 0.45 Ω (Pch + Nch DMOS)
  • Forward, reverse, brake, current limit control,
    high-side current monitor, diagnostic output,
    initial diagnosis
  • Through-current protection
  • Operating voltage range: 4.5 to 28 V
  • Operating temperature range: –40 to 125°C
  • Package: PQFN28 (6 mm x 6 mm)
