Monolithic Power Systems — MP6600L Stepper Motor Driver

The Monolithic Power Systems MP6600L is a stepper motor driver which implements current regulation and includes a built-in voltage translator.

Helping to reduce component count and simplify the board layout, the MP6600L features two internal full-bridge drivers, and includes a current sensor, eliminating the need for external sense resistors. Supplied in a 4mm x 4mm QFN package, the MP6600L is a space-saving, cost-effective solution for bipolar stepper motor drives.

The MP6600L operates from a supply-voltage range of 4.5V-35V, and can supply current of up to 1.5A to the motor. The device can operate a bipolar stepper motor in full-, half-, quarter-, or eighth-step mode.

Protection functions implemented in the driver include over-current protection, input over-voltage protection, under-voltage lock-out, and thermal shut-down.
