MONOLITHIC POWER SYSTEMS (MPS) EV6509-F-00A

Evaluation board for the MP6509GF bipolar stepper motor driver with dual, built-in full bridges consisting of N-channel power MOSFETs. The device operates from a 2.7V to 18V supply voltage range and can deliver output currents up to 1.2A per channel. The safety features include sink and source current limits implemented with external sensors, undervoltage lockout (UVLO) and thermal shutdown. An over-temperature output flag is available to indicate thermal shutdown. The board is a fully assembled and tested PCB. The input control signals for the MP6509 are applied through the connector or generated on the board. The board can drive a bipolar stepper motor with both full step and half-step mode. It also can drive two independent DC motors. Typical applications include POS printers, video security cameras, battery-powered devices and USB powered devices.
