SLA7072MPRT

Overview

The SLA7072MPRT is a fully integrated unipolar stepper motor driver manufactured by Sanken Electric USA Inc. It utilizes power MOSFET technology to combine control and power stages in a single component. The device supports 2-phase and 1-2 phase excitation modes with an internal sequencer. It operates with a supply voltage range of 3V to 5.5V and handles load voltages from 10V to 44V. The output current capability is rated at 2A per channel. It features step resolutions including full, half, quarter, eighth, and sixteenth steps. The unit is housed in a 23-ZIP (SLA) package designed for through-hole mounting.

Procurement Notes

Verify the exact part number suffix against official Sanken Electric documentation to ensure correct packaging and variant specifications. Confirm that the 23-ZIP form factor matches your PCB layout requirements. Check RoHS compliance status if required for your specific manufacturing standards. Ensure supply chain sources provide genuine components to avoid counterfeit risks associated with power management ICs.

Selection Notes

Select this component when designing circuits for unipolar stepper motors requiring integrated drive capabilities. It is suitable for applications needing low-voltage logic control interfacing with higher voltage motor loads. Consider the thermal performance of the 23-ZIP package for your expected current loads. Verify that the 2A output rating meets the motor coil requirements without exceeding junction temperature limits.
