MP6545A - Simple Three-Phase Power Stage

General 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.

Key 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.

MP6545A 45V, 2.5A, Simple Three-Phase Power Stage with Current Measurement 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.
