• Bidirectional DC motor control
• General purpose industrial applications

Motor Drivers, Controllers Procurement Notes

Verify the specific suffix EBTR against the official datasheet to confirm the 44-PLCC package configuration. Confirm RoHS compliance status as historical data indicates non-compliance for this variant. Check component lifecycle status, as listings indicate the product may be discontinued or obsolete. Ensure the supplier provides valid traceability documentation for legacy components.

Motor Drivers, Controllers Selection Notes

Select this component when a high-voltage bipolar stepper driver with integrated PWM control is required in a PLCC package. Compare against the UDN2916LB series if a smaller SOIC footprint is preferred. Verify that the 750mA output current meets the specific motor winding requirements. Ensure the system design accommodates the thermal characteristics associated with the 44-pin leaded ceramic package.

Motor Drivers, Controllers Part Context

This part belongs to the UDN2916 family of dual full-bridge motor drivers designed for bipolar stepper motors. It integrates internal clamp diodes and thermal shutdown circuitry. The device is functionally similar to other legacy Allegro drivers like the PBL3717. It serves as a complete solution for motor control without requiring external logic-level translation.
