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.
