DESCRIPTION

The MPQ6631H 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 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 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 is available in a TQFN-26

(3mmx4mm) package with wettable flanks. It is

available in AEC-Q100 Grade 1.
