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
Automotive applications such as a throttle valve control, various engine valves, retractable door mirrors, and a body system including an electric door latch, etc.
