MP6652A Description
The MP6652A is a single-phase brushless DC (BLDC) fan driver with integrated power MOSFETs and a Hall-effect sensor. It supports up to 1A of peak current across a wide 3V to 18V input voltage (VIN) range. The fan speed is controlled by a pulse-width modulation (PWM) signal applied on the PWM pin.
