UDN2916EBTR-T Equivalent & Substitute Parts

Part Overview

The UDN2916EBTR-T is a bipolar motor driver IC manufactured by Allegro MicroSystems, designed for fully integrated control and power stage applications in brushed DC and bipolar stepper motor systems. This component operates as a half-bridge driver with parallel interface control, supporting output currents up to 750mA and load voltages between 10V and 45V.

The UDN2916EBTR-T is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support legacy system maintenance or redesign initiatives.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the UDN2916EBTR-T are selected based on functional equivalence across the following critical parameters:

Motor control capability (bipolar stepper and brushed DC support), fully integrated driver architecture with control and power stages, half-bridge output configuration with four outputs, parallel interface control, and surface mount packaging. Load voltage range compatibility (minimum 9V to 32V for LV8735V-TLM-H; 10V to 45V for original) and output current capacity (1A for LV8735V-TLM-H versus 750mA for original) determine application suitability. Supply voltage operating ranges, package form factors, and regulatory compliance (RoHS3, REACH) are additional selection criteria.

The LV8735V-TLM-H (onsemi) and LV8746V-TLM-E (Sanyo) are identified as manufacturer-recommended substitutes based on functional motor driver architecture and control interface compatibility.

Parameter Comparison

Engineering Selection Recommendations

The LV8735V-TLM-H (onsemi) provides functional motor driver equivalence with enhanced output current capacity (1A versus 750mA) and extended supply voltage range (0V ~ 5.5V). This substitute maintains bipolar stepper and brushed DC motor support with half-bridge output configuration and parallel interface control. Both the original UDN2916EBTR-T and LV8735V-TLM-H are classified as obsolete; however, the LV8735V-TLM-H maintains ROHS3 compliance and MSL 3 rating. Package transition from 44-LCC to 44-LSSOP requires PCB layout modification.

The LV8746V-TLM-E (Sanyo) is listed as an active product and manufacturer-recommended substitute. Limited technical parameter data is provided for this component; detailed datasheet review is required to confirm functional equivalence and application compatibility.

For applications requiring extended operating temperature range (-20°C ~ 150°C), the LV8735V-TLM-H operating range (-40°C ~ 85°C ambient) may not satisfy thermal requirements. Load voltage compatibility must be verified: the LV8735V-TLM-H supports 9V ~ 32V, which is narrower than the original 10V ~ 45V range.

Frequently Asked Questions (FAQ)

Q: Can the LV8735V-TLM-H directly replace the UDN2916EBTR-T without design changes?

A: Functional replacement is possible based on motor driver architecture and control interface compatibility. However, package transition from 44-LCC to 44-LSSOP requires PCB layout modification. Load voltage range is reduced (9V ~ 32V versus 10V ~ 45V), which must be verified against application requirements.

Q: What are the key differences between the UDN2916EBTR-T and LV8735V-TLM-H?

A: The LV8735V-TLM-H offers higher output current (1A versus 750mA), extended supply voltage range (0V ~ 5.5V), and BiCDMOS technology versus bipolar. Operating temperature range is narrower (-40°C ~ 85°C ambient versus -20°C ~ 150°C junction). Load voltage maximum is reduced from 45V to 32V.

Q: Is the LV8746V-TLM-E suitable as a substitute?

A: The LV8746V-TLM-E is listed as an active product and manufacturer-recommended substitute. Comprehensive technical parameter data is not provided in this reference. Datasheet review and functional verification are required to confirm compatibility with specific application requirements.

Q: What packaging considerations apply to substitution?

A: The original UDN2916EBTR-T uses 44-LCC (J-Lead) surface mount packaging. The LV8735V-TLM-H uses 44-LSSOP (0.220", 5.60mm Width) with exposed pad. PCB footprint, trace routing, and thermal management design must be updated accordingly.

Q: Are both substitutes RoHS3 compliant?

A: The UDN2916EBTR-T and LV8735V-TLM-H are both ROHS3 compliant with MSL 3 rating. RoHS compliance status for the LV8746V-TLM-E is not specified in available data.
