TB9053FTG,TB9054FTG
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.
3. Features
● Motor driver block: 2-channel H-bridge driver (Ron(Nch+Nch)) = 142 mΩ (Typ. @Tj = 25°C, VBAT = 8 V) 2-channel mode and combined 2-channel mode selectable ● Detection features: Over-current detection, over-temperature detection, VBAT under- voltage detection, and VCC under-voltage detection ● Initial diagnosis: Power supply fault detection circuit (VBAT under-voltage and VCC under-voltage) ● PWM control output ● Forward/reverse/brake modes ● Current limit control: Chopper-type current limiter ● Hi-side output current monitoring function (CM1 and CM2 pins) ● Open-load detection: During operation/non-operation ● Diagnosis output (DIAG1 and DIAG2 pins) ● H-bridge mode/Half-bridge mode selectable with OSEL1 and OSEL2 ● Low-power sleep mode ● Through-current prevention circuit This is a reference document.
