MPS EVQ6541A-QK-00A Manual

DESCRIPTION

The EVQ6541A-QK-00A is an evaluation board
designed to demonstrate the capabilities of the
MPQ6541A, a three-phase
(BLDC) motor driver. It operates from a wide
4.75V to 40V input voltage range.
The MPQ6541A has three integrated half-
bridges consisting of six N-channel power
MOSFETs. The rotor position information is
provided by the Hall sensors assembled in the
motor. The driver control signals are generated
via an external controller, such a microcontroller
unit (MCU) or field-programmable gate array
(FPGA).
The MPQ6541A is available in a QFN-26
(6mmx6mm) package.
