The Toshiba next-generation combination motor driver ICs feature low noise, high-speed and high-accuracy control for general purpose and battery-powered applications. Using proprietary production and circuit technologies, the ICs are designed for different drive modes, can support DC motors as well as stepper motors and can be used to drive several motors with one chip. High-speed and efficient power control is achieved with PWM, constant-current or direct PWM, on the order of several hundred kHz. The devices are available with an independent, power-saving, standby-mode control function, a through current prevention function for the output driver section by dead time control (Typ.= 300 ns), a built-in thermal shutdown (TSD) circuit, and a Vcc power supply under voltage detection (UVLO) circuit.
