DESCRIPTION

The MP6545A is a three-phase power stage IC

designed to drive brushless DC (BLDC) motors

or other loads.

The MP6545A operates across a 4.5V to 45V

input voltage (VIN) range. It can deliver an

output current (IOUT) up to 2.5A per phase,

depending on the ambient temperature (TA) and

PCB layout.

The MP6545A has unique, independent GND

pins for each half-bridge. These GND pins

make it possible to provide current

measurement via an external shunt resistor for

different application requirements.

Internal safety and diagnostic features include

over-current protection (OCP), input overvoltage protection (OVP), input under-voltage

lockout (UVLO), and thermal shutdown.

The MP6545A has separate high-side (HS) and

low-side (LS) input pins for each output pin. The

MP6545A is available in QFN-28 (4mmx5mm)

and TSSOP-28EP packages.
