Able to drive both windings of a bipolar stepper motor, or bidirectional control of 2 DC motors
Load voltage supply range: 10V to 40V
Output current up to 750mA (each bridge)
Internal fixed Toff time PWM current control
Built-in protection diodes
Internal thermal shutdown
Under-voltage lockout
LS-TTL compatible logic inputs with pull-up resistors
Low RON output resistance

Three-Phase BLDC Fan Motor Controllers
Microchip also offers a family of sensorless sinusoidal drivers for three-phase BLDC fan motors. This
family of fan controllers can be interfaced with any microcontroller by using a simple PWM, or can also be
used stand alone by the application.
