SS30-TE-L-E Motor Driver IC - Equivalent & Substitute Parts

Part Overview

The SS30-TE-L-E is a Bi-CMOS PWM motor driver IC manufactured by onsemi, designed for brushless DC (BLDC) motor applications with integrated control and power stage functionality. This device operates across a 2.2V to 6V supply range and delivers 700mA output current through a half-bridge (3) configuration. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SS30-TE-L-E is determined by the following critical parameters:

• Motor Driver Function: Fully integrated control and power stage for BLDC motor applications
• Output Configuration: Half bridge (3) topology
• Interface Protocol: PWM control
• Package Type: 20-pin QFN form factor with surface mount capability
• Voltage Operating Range: Supply and load voltage compatibility within 2.2V to 6V envelope
• Output Current Capability: Minimum 700mA delivery requirement
• Thermal Operating Range: Functional operation across -30°C to 95°C

The A4942GESTR-T from Allegro MicroSystems meets these substitution criteria through equivalent BLDC motor driver architecture, identical half-bridge (3) output configuration, PWM interface compatibility, and compatible 20-pin QFN package footprint.

Parameter Comparison

Engineering Selection Recommendations

The A4942GESTR-T qualifies as a direct functional substitute for the obsolete SS30-TE-L-E based on:

• Identical BLDC motor driver architecture with fully integrated control and power stage
• Matching half-bridge (3) output topology and PWM interface
• Compatible 20-pin QFN surface mount package footprint
• Extended operating temperature range (-40°C to 105°C) that encompasses the original specification
• Active product status with ongoing manufacturer support and availability

The A4942GESTR-T is supplied in Tape & Reel packaging with RoHS3 compliance and MSL 2 (1 Year) moisture sensitivity rating, suitable for production environments. Both parts carry identical REACH Unaffected and EAR99 export classification status.

Frequently Asked Questions (FAQ)

Q: Can the A4942GESTR-T directly replace the SS30-TE-L-E in existing designs?

A: Yes. Both devices share identical output configuration (half-bridge 3), PWM interface, and 20-pin QFN package footprint. Pin-level compatibility requires verification against device datasheets to confirm signal mapping and functional pin assignments.

Q: What is the primary reason for substitution?

A: The SS30-TE-L-E is classified as obsolete. The A4942GESTR-T is an active product with current manufacturer support, ensuring long-term availability and supply chain continuity.

Q: Are there package differences between these parts?

A: Both use 20-pin QFN packages. The A4942GESTR-T includes an exposed pad variant (20-QFN-EP 4x4), which may provide improved thermal performance compared to the standard 20-WFQFN. PCB layout modifications may be required to accommodate the exposed pad.

Q: How do the voltage and current specifications compare?

A: The SS30-TE-L-E specifies 700mA output current and 2.2V to 6V supply/load voltage range. The A4942GESTR-T datasheet does not list these parameters in the provided data. Detailed electrical specifications must be obtained from the Allegro MicroSystems A4942GESTR-T datasheet to confirm output current capability and voltage operating range.

Q: What are the compliance and certification differences?

A: The SS30-TE-L-E carries MSL 1 (Unlimited) moisture sensitivity. The A4942GESTR-T carries MSL 2 (1 Year), requiring controlled storage conditions. Both parts are REACH Unaffected and EAR99 classified. The A4942GESTR-T is RoHS3 compliant.
