TB67B000AHG
TOSHIBA Bi-CMOS Power Integrated Circuit Multi-Chip Package (MCP)
TB67B000AHG
High voltage
3-Phase Full-Wave PWM Brushless Motor Driver
The TB67B000AHG is a high-voltage PWM brushless motor
driver. The product integrates a controller, which supports
sine-wave PWM drive and wide-angle commutation and a
high-voltage driver in a single package (“two-in-one”, i.e. MCP).
It is designed to change the speed of a brushless motor directly
by using a speed control analog signal from a microcontroller.
