A3959SLPTR-T

Overview

The A3959SLPTR-T is a brushed DC motor driver manufactured by Allegro Microsystems, designed for surface-mount applications in a 28-pin TSSOP-EP package. It features a dual half-bridge output configuration with a maximum continuous output current of 3A and supports load voltages ranging from 9.5V to 50V. The device operates on a supply voltage between 4.5V and 5.5V, utilizing parallel interface control. It employs DMOS technology and functions within an operating temperature range of -20°C to +150°C (junction temperature).

Feature Summary

Integrates full control logic and power stages into a single monolithic IC.
Supports bidirectional control of brushed DC motors via parallel interface.
Includes built-in protection mechanisms against overcurrent and thermal overload.

Applications

Brushed DC motor control systems
General-purpose motion control applications
Industrial automation actuators

Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging when ordering. Confirm that the 28-TSSOP-EP package matches the target PCB footprint, particularly regarding the exposed pad for thermal dissipation. Ensure the design accommodates the specified 4.5V to 5.5V logic supply voltage distinct from the higher motor load voltage range.

Selection Notes

Select this component for applications requiring integrated brushed DC motor drive with parallel control signals. It is suitable where a compact 28-pin surface-mount form factor is preferred over larger packages. Consider the 3A current limit and 50V voltage rating to ensure compatibility with the intended motor specifications and system power rails.

Part Context

This part belongs to the A3959 series of motor drivers from Allegro MicroSystems. It shares functional similarities with other devices in the family but is distinguished by its specific 28-TSSOP-EP package and parallel interface configuration. It serves as a complete solution for driving brushed DC motors without requiring external discrete power components.
