TB6552FN/FL is a dual-bridge driver IC for DC motor with output transistor in LD MOS structure with low ON-resistor. Two input signals, IN1 and IN2, can chose one of four modes such as CW, CCW, short brake, and stop mode. Efficient driven at high temperature is possible by PWM drive system.
The document describes the Toshiba TB6552FN/FL, a dual-bridge driver integrated circuit intended for driving DC motors. The device features an LD MOS structure with low ON-resistance and supports four operating modes: continuous forward (CW), continuous reverse (CCW), short brake, and stop.
Key specifications include a maximum motor supply voltage of 15V, a control supply voltage range of 2.7V to 6.0V, and a maximum output current of 1A per channel. The IC supports direct PWM control for speed regulation and includes built-in thermal shutdown protection.
