A4955KLPTR-T

Overview

The A4955KLPTR-T is a brushed DC motor gate driver manufactured by Allegro MicroSystems. It operates within a supply voltage range of 5.5V to 50V and supports an ambient operating temperature from -40°C to 125°C. The device features a parallel interface and utilizes NMOS technology for its output stage. It is packaged in a 20-TSSOP-EP (Exposed Pad) configuration, measuring 4.40mm in width. This component holds AEC-Q100 automotive qualification and complies with RoHS3 standards.

Feature Summary

Integrated controller functionality providing commutation and direction management capabilities
Dual half-bridge pre-driver output configuration designed for driving external power stages
Automotive-grade reliability certified under the AEC-Q100 standard

Applications

Brushed DC motor control systems
Automotive electronic applications requiring qualified components
General purpose motor drive circuits

Procurement Notes

Verify the specific suffix KLPTR-T against official datasheets to confirm package type and tape-and-reel specifications. Confirm that the intended design accepts the 'Not Recommended for New Designs' status if applicable. Ensure compatibility with the 20-TSSOP-EP footprint and exposed pad thermal requirements during procurement planning.

Selection Notes

Select this component when designing brushed DC motor drivers requiring automotive qualification and a wide input voltage range up to 50V. The parallel interface suits applications needing direct digital control without complex serial protocols. Consider the exposed pad package for thermal management needs in high-current scenarios.

Part Context

This part belongs to the A4955 series of gate drivers from Allegro MicroSystems. It is specifically engineered for brushed DC motor applications rather than stepper or AC motors. The series emphasizes robust performance in automotive environments, distinguishing it from general-purpose industrial drivers through its specific qualification standards.
