PWM type 2-channel H-Bridge DC brushed motor driver for automotive application
TB9053FTG 1. Outline
TB9053FTG and TB9054FTG incorporates in each two
channels of output driver for the direct drive of a DC brushed
motor for automotive application. The PWM control with low on-resistance enables highly
P-QFN40-0606-0.5
efficient motor drive output.
Forward, reverse, or brake mode can be selected for motor 1
TB9054FTG
using the PWM1 and PWM2 pins, and for motor 2 using the
PWM3 and PWM4 pins. The ENABLE pins (EN1/ENB1 and
EN2/ENB2) can select motor drive or stop mode.
The devices can control the motor 1 speed by PWM signal
duty to PWM1/PWM2 pins or through SPI registers, that is
selectable with ISEL1 input signal.
The devices can control the motor 2 speed by PWM signal
P-VQFN40-0606-0.5
duty to PWM3/PWM4 pins or through SPI registers, that is
selectable with ISEL2 input signal.
The output current capacity is 6.5 A (typ.), which is suitable for a wide range of automotive
applications such as a throttle valve control, various engine valves, retractable door mirrors, and a
seat positioning. 2. Application …
