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. The MP6652A’s configurable speed curve makes this device well-suited for cooling fan applications that require flexible speed curve control.
The FG/RD pin is an open-drain output that can be configured for speed detection (FG) or locked rotor protection (RD). The FG/RD pin must be pulled up externally.
Rich protections are implemented for robust operation. These protections include input over-voltage protection (OVP), under-voltage lockout (UVLO), locked rotor protection, thermal shutdown, and over-current protection (OCP).
The MP6652A is available in TSOT23-6-SL and TSOT23-6-R packages.
