The MP9518 is a single-phase, brushless, DC motor driver with integrated power MOSFETs and a hall-effect sensor.

Product Detail

The MP9518 is a single-phase, brushless, DC motor driver with integrated power MOSFETs and a hall-effect sensor. The MP9518 drives single-phase, brushless, DC fan motors with up to 1.2A of output current limit. The IC has a 3.3V to 18V input voltage range and input line reverse-voltage protection to save the external diode on the supply line. The MP9518 controls the rotational speed through the PWM signal on the PWM pin. The MP9518 has a rotational speed detector feature and rotor lock fault indication on FG/RD with an open-drain collector output. The output speed versus the input duty curve can be programmed easily for flexible use. To reduce fan driver audible noise and power loss, the MP9518 features a soft on/off phase transition and automatic phase-lock function of the motor winding BEMF and current. Full protection features include input over-voltage protection (OVP), under-voltage lockout (UVLO), rotor deadlocked protection, thermal shutdown, and input reverse protection. The MP9518 requires a minimal number of external components to save solution cost. The MP9518 is available in a TSOT23-6 package.
