Overview
The MP6601GF-Z is a fully integrated bipolar stepper motor driver manufactured by Monolithic Power Systems Inc. It features a power MOSFET technology and 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 utilizes a logic interface and provides four half-bridge outputs. The component is housed in a 28-TSSOP-EP package with exposed pads and functions within a junction temperature range of -40°C to 125°C.
Feature Summary
- Fully integrated design combining control logic and power stages for simplified implementation
- Supports multiple stepping modes including full, half, quarter, and eighth steps
- Built-in protection mechanisms inherent to the integrated power MOSFET architecture
Applications
- Printers
- Bipolar stepper motor control systems
- Automated positioning devices
Procurement Notes
Verify the specific suffix (e.g., Z or P) against the required RoHS compliance and lead time requirements. Confirm the 28-TSSOP-EP package dimensions match the PCB footprint. Ensure the 4.5V to 35V input range aligns with the system power supply. Check thermal dissipation capabilities given the 2.5A output capability in the selected package.
Selection Notes
Select this component when a compact, fully integrated solution for bipolar stepper motors is required. The 2.5A output current rating suits moderate load applications. Consider the 28-TSSOP-EP package for surface mount assembly with enhanced thermal performance via the exposed pad. Verify compatibility with the system's logic voltage levels and required step resolution settings.
Part Context
The MP6601 belongs to Monolithic Power Systems' portfolio of power management and motor control integrated circuits. This series targets applications requiring efficient drive for bipolar stepper motors without external discrete power components. The MP6601GF variant specifically denotes the tape and reel packaging configuration suitable for automated manufacturing processes.
Replacement Considerations
MP6500GF-Z is documented as a parameter equivalent substitute.
