The MC121-Q1 is a 40V, 850mΩ rated motor driver with integrated N-channel full-bridge, charge pump, Hall sensor, commutation control logic, and protection circuitry for single phase brushless DC motors. The Hall sensor provides rotor position information to the commutation logic to maintain continuous rotor motion. The commutation logic can be programmed for square and soft PWM waveforms to reduce acoustic noise or maximize speed/efficiency.

The duty cycle of a pulse-width modulated signal or a (0-3)V DC voltage on the PWM/DC pin controls the motor speed. FG/RD pin can be configured to report the motor speed or a locked rotor condition to an external controller. The PWM/DC and FG/RD pins can be temporarily configured as an I2C interface to support a programming (OTP) mode to configure the OTP during production.

The MC121-Q1 integrates protection features for motor and device protection. These include supply undervoltage lockout, overvoltage protection, output overcurrent protection, device overtemperature shutdown, and locked rotor protection.

The MC121-Q1 is available in two 6-pin packages: SOT23-FL and X2SON. SOT23-FL is a flat lead package with a maximum height of 1.1mm. X2SON is a non-leaded package with a max. height of 0.4mm.
