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.
