Monolithic Power Systems — MP6603 55 V Dual Full-Bridge Motor Driver

 

Monolithic Power Systems MP6603 55V Dual Full-Bridge Motor Driver

Featuring integrated low-on resistance (RDS(ON)) MOSFETs.

The MP6603 from Monolithic Power Systems is a dual full-bridge motor driver that features integrated low (RDS(ON)) MOSFETs.

With its compact QFN package and high level of integration, the MP6603 offers a cost-efficient solution for driving brushed DC motors and stepper motors.

It supports an input voltage range from 8V to 55V and is capable of supplying up to 5A peak motor current per full bridge, depending on PCB layout and ambient temperature.

A notable feature of the MP6603 is its independent ground pins for each half-bridge, enabling current sensing via external shunt resistors.

The device offers two selectable input control modes: a pulse-width modulation (PWM) interface and an indexer interface, configurable using the IN_SEL pin.

Built-in protection and diagnostic capabilities include over-current protection (OCP), short-circuit protection (SCP), under-voltage protection (UVP), and thermal shutdown.

The MP6603 comes in a space-saving 25-pin QFN package measuring 4mm x 5mm.

EV6603-V-00A Evaluation Board

EV6603-V-00A Evaluation Board
EV6603-V-00A

The EV6603-V-00A by Monolithic Power Systems is an evaluation board designed to demonstrate the capabilities of the MP6603, a dual full-bridge motor driver with a built-in, microstepping translator.

The MP6603 operates from a supply voltage of up to 55V, and it can deliver a motor current up to 5A. It can drive one or two DC motors or a bipolar stepper motor in full-, half-, quarter-, and eighth-step modes by setting M2 and M1. The input control signals for the MP6603 are applied through the CN1 connector or generated on the board.

The MP6603 is available in a QFN-25 (4mmx5mm) package. It is recommended to read the MP6603 datasheet prior to making any changes to the evaluation board
