A4926KLPTR-T

Overview

The A4926KLPTR-T is a half-bridge MOSFET gate driver manufactured by Allegro MicroSystems. It operates within a supply voltage range of 5.5 V to 50 V and supports junction temperatures from -40°C to +150°C. The device features non-inverting inputs with logic thresholds of 0.8 V (VIL) and 2 V (VIH). Packaged in a 20-TSSOP-EP surface-mount format, it provides independent channel control for N-channel MOSFETs.

Feature Summary

• Half-bridge configuration designed for driving N-channel power MOSFETs
• Non-inverting input logic interface compatible with standard control signals
• Automotive-grade thermal performance supporting high junction temperatures

Applications

• Brushed DC motor control systems
• Solenoid actuation drivers
• General-purpose power switching applications

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm that the 20-TSSOP-EP package includes an exposed thermal pad for heat dissipation. Ensure the supply voltage remains within the 5.5 V to 50 V operational limits during system integration.

Selection Notes

Select this component for applications requiring independent half-bridge control with simple non-inverting logic. It is suitable for designs needing robust thermal operation up to 150°C. Consider the TSSOP-EP package for its balance of pin count and thermal management capabilities in compact layouts.

Part Context

This part belongs to the A4926 series of gate drivers from Allegro MicroSystems. It is categorized under PMIC and MOSFET Gate Drivers. The device is distinct from full-bridge or multi-phase drivers, focusing specifically on single half-bridge functionality for precise power stage control.

Replacement Considerations

Direct substitutes include other Allegro half-bridge drivers such as the A4925 or A4927 if pin compatibility and electrical specifications align. Verify that alternative parts support the same 5.5 V to 50 V supply range and N-channel MOSFET drive requirements.
