Microcontrollers For Automotive Motor Control - Toshiba TLCS-900 Family Product Manual

Microcontrollers for automotive motor control

These microcontrollers incorporate an inverter control function for
sensorless/sensor-equipped 3-phase DC and AC motors and a sine
wave drive circuit for supporting high reliability and high temperature
operation. The sine wave drive circuit enables easy sine wave drive
suited to high efficiency and low noise.
Achieved intelligent, high value-added automotive motors!
