DESCRIPTION

The MPQ6653-AEC1 is a single-phase

brushless DC (BLDC) motor driver with

integrated power MOSFETs and an embedded

Hall sensor. It drives a single-phase BLDC

motor, with up to 1.2A of phase peak current.

The input voltage (VIN) range is between 5.5V

and 35V.

The MPQ6653-AEC1 controls the motor speed

through the pulse-width modulation (PWM)

signal or the DC voltage on the PWM pin. The

device features configurable soft commutation

and a Hall offset angle that can flexibly optimize

performance.

The MPQ6653-AEC1 also provides rotational

speed detection. The rotational speed detector

(the FG/RD pin) is an open-drain output that

outputs a high or low voltage relative to the

internal Hall comparator’s output.

Rich protections include input over-voltage

protection (OVP), under-voltage lockout (UVLO),

locked-rotor protection, over-current protection

(OCP), and thermal shutdown protection.

The MPQ6653-AEC1 is available in TSOT23-6-

SL and TSOT23-6 packages, and it is available

in AEC-Q100 Grade 1.
