Overview
The Allegro MicroSystems UDQ2916EB is a dual full-bridge PWM motor driver designed for bipolar stepper motors or bidirectional DC motor control. It operates on a single supply voltage ranging from 4.75V to 5.25V, with load voltages supported between 10V and 45V. The device delivers an output current of 750mA per channel. It features an operating junction temperature range of -40°C to +150°C and is available in surface-mount packaging.
Feature Summary
- Integrates protection logic to reduce component count in stepper motor control applications
- Supports pulse width modulation (PWM) fixed off-time peak current control
- Provides diagnostic output signals for overtemperature and overcurrent events
Applications
- Industrial automation systems
- Office equipment motor control
- Retail point-of-sale mechanisms
- Medical device actuation
Procurement Notes
Verify the specific suffix variant against official datasheets, as designations like UDN2916B or UDN2916LB may indicate distinct pinouts or electrical characteristics. Confirm package type compatibility, such as SOIC W or PLCC, prior to integration. Ensure thermal management requirements align with the specified junction temperature limits during operation.
Selection Notes
Select this component when a single-supply solution is required for driving bipolar stepper motors or two DC motors. The integrated charge pump and current sensing simplify circuit design by minimizing external components. Consider the wide operating temperature range for environments requiring robust thermal performance without additional cooling infrastructure.
Part Context
This part belongs to the Allegro MicroSystems family of low-voltage motor drivers. Similar devices include the A3916, which offers higher current capabilities and different packaging options. The UDQ2916EB series is engineered for cost-sensitive applications requiring reliable motor control with minimal external support circuitry.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify pin-to-pin compatibility with legacy parts like UDN2916 variants before substitution.
