TB9053FTG,TB9054FTG Bi-CMOS Linear Integrated Circuit, Silicon Monolithic TB9053FTG,TB9054FTG PWM-type, dual-channel, H-bridge, brushed DC motor driver for automotive application TB9053FTG 1. Overview TB9053FTG and TB9054FTG integrated circuit (IC) incorporates in each two output driver channels for direct drive of a brushed DC motor for automotive application. PWM control with low on-resistance enables highly efficient P-LQFN40-0606-0.50-001 motor drive output. The PWM1 and PWM2 pins specify forward, reverse, or brake TB9054FTG modes for motor 1, and the PWM3 and PWM4 pins specify these modes for motor 2. The ENABLE pins (EN1/ENB1 and EN2/ENB2) specify drive or stop mode for the motor. The ISEL1 pin specifies whether the motor drive uses the PWM1 and PWM2 pins or SPI. The ISEL2 pin specifies whether the motor drive uses the PWM3 and PWM4 pins or SPI. P-VQFN40-0606-0.50-004 The output current capacity is 6.5 A (typ.), which is suitable for a P-VQFN40-0606-0.5 wide range of automotive applications such as control of the throttle valve, various engine valves, retractable door mirrors, and seat heater. 2. Application Automotive applications such as control of the throttle valve, various engine valves, retractable door mirrors, and seat heater. 3. Features Motor driver block: Dual-channel, H-bridge driver (Ron(Nch+Nch)) < 350 m (Max Tj = 150C, VBAT = 8 V) Dual-Channel Mode and Combined-Channel Mode selectable, connecting two outputs externally allows this IC to function as a single-channel H-bridge circuit and the device is also used as a 4-channel Half Bridge driver. 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 High-side output current monitoring function (CM1 and CM2 pins) Open-load detection: During operation/non-operation DIAG output (DIAG1 and DIAG2 pins) H-Bridge Mode/Half-Bridge Mode selectable (OSEL1 and OSEL2 pins) Low-power Sleep Mode Through-current prevention circuit AEC-Q100/AEC-Q006 Capable 2020-2022 1 2022-08-29 Toshiba Electronic Devices & Storage Corporation Rev. 1.1 TB9053FTG,TB9054FTG SPI communication: fault reporting, device settings and motor control through the SPI registers Operating voltage range: VBAT = 4.5 to 28 V (absolute rating of power supply voltage = 40 V (max.)
