STK672-081-SD-E

Overview

The STK672-081-SD-E is a hybrid integrated circuit manufactured by onsemi, classified as a stepper motor driver within the PMIC category. It is designed for unipolar, two-phase stepper motor applications with PWM current control capabilities. The component features built-in protection mechanisms including overcurrent and overheat detection functions that trigger an active low fault signal. It incorporates a power-on reset function and simultaneous on prevention to ensure reliable operation. The device supports Schmitt input characteristics compatible with 2.5V high-level logic inputs.

Feature Summary

Built-in overcurrent and overheat detection functions with automatic output current cutoff
Active low fault signal output for system monitoring during abnormal conditions
Power-on reset function ensures stable initialization upon voltage application
Simultaneous on prevention mechanism protects against bridge shoot-through

Applications

Office photocopiers
Printers
Unipolar stepper motor control systems

Procurement Notes

Verify component authenticity through authorized distributors or certified secondary market suppliers such as Rochester Electronics, LLC, due to the part's discontinued status. Confirm manufacturing date codes and physical condition prior to integration. Ensure compatibility with existing PCB footprints and thermal management requirements. Validate that the specific SD-E suffix matches design specifications without functional deviations from original datasheet parameters.

Selection Notes

Select this component for designs requiring robust protection in unipolar stepper motor drives. Evaluate thermal dissipation needs as the device includes internal power MOSFETs. Consider the SIP package constraints for board layout. Verify that the external resistor configuration for current setting aligns with the target motor specifications. Ensure the supply voltage range meets the operational requirements of the host system.
