Overview
The UDQ2916LB is a dual full-bridge PWM motor driver designed for bipolar stepper motors or bidirectional DC motor control. It features internal pulse-width modulation (PWM) current control, sustaining up to 45 V output voltage with a continuous output current of 750 mA. The device includes low output saturation voltage drop and internal clamp diodes. Logic-level inputs allow selection of output current limits at 0, 33, 67, or 100% of the maximum level. A PHASE input determines load current direction for each bridge.
Feature Summary
- Integrates dual full-bridge drivers with internal PWM current control for precise regulation
- Includes internal thermal shutdown circuitry and clamp diodes for protection
- Features logic-level inputs for programmable current limit selection and direction control
Applications
- Bipolar stepper motor drive systems
- Bidirectional DC motor control applications
- Tax control market micro-printer motor control
Procurement Notes
Verify component authenticity through authorized Allegro MicroSystems distributors. Confirm package type matches SOIC W specifications. Check RoHS status as some variants may not comply. Validate operating temperature range requirements against datasheet limits before procurement.
Selection Notes
Select this component when driving bipolar stepper motors or bidirectional DC loads requiring integrated PWM current control. Ensure supply voltage stays within 4.75 V to 5.25 V range. Verify that external sensing resistor values align with desired current limits. Consider thermal management due to integrated power stage characteristics.
Part Context
UDQ2916LB belongs to Allegro's 2916 series of dual full-bridge motor drivers. It serves as an alternative to similar devices like PBL3717 and UC3770. The part integrates control and power stages, reducing external component count compared to discrete solutions.
Replacement Considerations
Public confirmed substitute part numbers include UDN2916LB-T and UDQ2916LBTR-T. These variants maintain functional compatibility while potentially differing in packaging or tape-and-reel configurations.
