MP6601GF-Z

Overview

The MP6601GF-Z is a bipolar stepper motor driver from Monolithic Power Systems, designed for full integration of control and power stages. It supports step resolutions of 1, 1/2, 1/4, and 1/8. The device operates with a supply voltage range of 4.5V to 35V and delivers an output current of 2.5A. It features four half-bridge outputs configured for bipolar stepper motors. The component utilizes logic interface inputs and is housed in a 28-TSSOP-EP package with exposed pad. It functions within a junction temperature range of -40°C to 125°C.

Feature Summary

• Full integration of control logic and power MOSFET stages for simplified design
• Supports multiple microstepping resolutions including full, half, quarter, and eighth steps
• Configured as a four-half-bridge driver specifically for bipolar stepper applications

Applications

• Printer mechanisms requiring precise stepper motor control
• Motion control systems utilizing bipolar stepper actuators
• Automated equipment needing integrated motor drive solutions

Procurement Notes

Verify the specific suffix 'Z' indicates RoHS compliance when sourcing. Confirm the 28-TSSOP-EP package dimensions match the PCB footprint requirements. Check moisture sensitivity level (MSL 2A) handling procedures during assembly. Ensure the supply voltage does not exceed the 35V maximum rating for reliable operation.

Selection Notes

Select this component for designs requiring integrated bipolar stepper driving without external discrete power transistors. The 2.5A output current capability suits moderate-load stepper applications. Consider the 28-pin TSSOP package for space-constrained layouts. Verify that the logic input levels are compatible with the system's microcontroller or FPGA outputs.

Part Context

This part belongs to the MP series of power management ICs from Monolithic Power Systems. It falls under the category of motor drivers and controllers within the PMIC classification. The device is distinct from low-side drivers like the MP6606 or H-bridge DC drivers like the MP6612 by its specific configuration for bipolar stepper motors.

Replacement Considerations

MP6601GF-P is listed as a parameter-equivalent alternative from the same manufacturer.
