DESCRIPTION

The MP6545 is a three-phase power stage IC

designed to drive brushless DC (BLDC) motors

or other loads.

The MP6545 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.

Internal safety and diagnostic features include

over-current protection (OCP), input overvoltage

protection (OVP), input under-voltage

lockout (UVLO), and thermal shutdown.

The MP6545 has separate high-side (HS) and

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

MP6545 is available in QFN-28 (4mmx5mm)

and TSSOP-28EP packages.
