MP6632
DESCRIPTION
The MP6632 is a three-phase brushless DC (BLDC) motor driver controller with up to 1A of driving current. It drives three-phase BLDC motors, with a 6V to 50V input voltage (VIN) range.
The MP6632 controls the motor speed through the pulse-width modulation (PWM) signal or the DC signal on the PWM/DC pin with closedloop/open-loop speed control. The device features a built-in, configurable speed curve function. It also features a sinusoidal drive for maximum torque, as well as low speed ripple and noise across the full speed range.
The MP6632 provides rotational speed detection. The rotational speed detector (the FG/RD pin) is an open-drain output. It outputs a high or low voltage relative to the Hall parator’s output. Direction control is achieved via the DIR pin’s input.
Rich protections include under-voltage lockout (UVLO), locked-rotor protection, over-current protection (OCP), and thermal shutdown protection.
The MP6632 is available in a QFN-32 (4mmx4mm)...
