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

 Download PSpice® model file

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.
