The MP9517 is a single-phase, brushless DC motor driver with integrated power MOSFETs and a Hall-effect sensor. The IC has a 3.3V to 18V input voltage range and input line reverse voltage protection. The MP9517 controls the rotational speed through the PWM signal on the PWM pin, with a 2kHz to 100kHz PWM frequency range. The MP9517 has a rotational speed detection feature on the FG pin, an open-drain output. To reduce fan driver audible noise and power loss, the MP9517 features soft-on/off phase commutation, and automatic control for winding BEMF and current zero-crossing with the same phase. Full protection features include input over-voltage protection (OVP), under-voltage lockout (UVLO), rotor deadlock protection, thermal shutdown, and input reverse protection. The MP9517 requires a minimal number of external components to reduce solution cost. It is available in a TSOT23-6-SL and TSOT23-6-L package.
