A4956GLPTR-T

Overview

The A4956GLPTR-T is a motor driver integrated circuit manufactured by Allegro MicroSystems. It utilizes NMOS technology and supports a supply voltage range of 5.5V to 50V. Designed for brushed DC motors, it features parallel interface control with built-in commutation and direction management functions. The device provides two half-bridge pre-drivers in a 20-TSSOP-EP package with an exposed pad. It operates within a temperature range of -40°C to 105°C.

Feature Summary

• Integrated commutation and direction management controller
• Dual half-bridge pre-driver output configuration
• Parallel interface for digital control signals

Applications

• Brushed DC motor control systems
• General purpose motor drive applications

Procurement Notes

Verify the specific suffix GLPTR-T against official Allegro MicroSystems documentation to confirm the tape and reel packaging format and pinout compatibility. Ensure the procurement source provides valid RoHS3 compliance data and moisture sensitivity level (MSL) information consistent with the manufacturer's current product status.

Selection Notes

Select this component when designing brushed DC motor drives requiring integrated commutation logic and parallel interface control. The 20-TSSOP-EP package offers thermal performance benefits for surface mount assembly. Confirm that the system power supply voltage remains within the specified 5.5V to 50V operating range.

Part Context

This part belongs to the A4956 series from Allegro MicroSystems. It is functionally related to other variants such as the A4956GESTR-T, which shares similar electrical characteristics but utilizes a different 20-QFN-EP package. The series targets general-purpose motor control applications requiring compact integration.

Replacement Considerations

The A4955GLPTR-T is listed as a parameter equivalent substitute by distributors.
