MPQ6631H-AEC1中文资料35V Input, 3A Peak Phase Current, 3-Phase BLDC Motor Driver, AEC-Q100 Qualified数据手册MPS规格书

描述 Description

The MPQ6631H-AEC1 is a three-phase, brushless DC (BLDC) motor driver with integrated power MOSFETs. The device supports a single external Hall sensor or three external Hall-effect sensors to drive a three-phase BLDC motor, with up to 3A of peak phase current and an input voltage (VIN) range between 3.6V and 35V.

The MPQ6631H-AEC1 controls the motor speed through the pulse-width modulation (PWM) signal or the DC signal on the PWM/DC pin with closed-/open-loop 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 MPQ6631H-AEC1 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 comparator’s output. Direction control is achieved via the DIR pin’s input.

Rich protection features include input overvoltage protection (OVP), under-voltage lockout (UVLO), locked-rotor protection, over-current protection (OCP), and thermal shutdown protection.

The MPQ6631H-AEC1 is available in a TQFN-26 (3mmx4mm) package with wettable flanks. It is available in AEC-Q100 Grade 1.
