UDQ2916LBTR

Overview

The Allegro MicroSystems UDQ2916LBTR is a bipolar stepper or brushed DC motor driver IC housed in a 24-SOIC package. It operates on a supply voltage of 4.75V to 5.25V and supports load voltages from 10V to 45V. The device delivers an output current of 750mA per channel with four half-bridge outputs. It features parallel interface control, integrated PWM current regulation, and over-current protection. The component functions within a junction temperature range of -40°C to +150°C.

Feature Summary

• Integrates full control and power stages for bipolar stepper and brushed DC motors
• Includes built-in PWM current control with fixed off-time regulation
• Provides diagnostic output signals for over-temperature and over-current events

Applications

• Bipolar stepper motor control systems
• Brushed DC motor drive applications
• General purpose motor driver circuits

Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging configuration against official Allegro documentation. Confirm RoHS compliance status as listed datasheets may indicate non-compliance for certain variants. Ensure the part number matches the exact manufacturer designation before procurement to avoid compatibility issues with existing designs.

Selection Notes

Select this component when a low-voltage (5V) bipolar motor driver is required with integrated current limiting. The 24-SOIC package suits surface-mount assembly processes. Consider the 750mA output capability and 45V load voltage limit for appropriate motor sizing. Verify thermal management requirements given the high operating temperature range.

Part Context

The UDQ2916 series belongs to Allegro's family of low-voltage bipolar motor drivers designed for office automation and industrial applications. These devices simplify motor control by integrating necessary logic and power stages into a single chip, reducing external component count compared to discrete solutions.

Replacement Considerations

UDQ2916LB is the base part number variant.
