Overview
The A4927KLPTR-T is an automotive half-bridge MOSFET gate driver manufactured by Allegro MicroSystems. It integrates a sense amplifier for current monitoring and protection. The device operates within a supply voltage range of 4.5 V to 50 V and supports junction temperatures up to +150 °C. It is housed in a 24-pin TSSOP package with exposed pad for thermal management. The component is designed for robust performance in harsh automotive environments, featuring low on-resistance switches and comprehensive fault protection mechanisms including overcurrent, overtemperature, and undervoltage lockout.
Feature Summary
- Integrates a high-side and low-side MOSFET driver with a built-in sense amplifier for precise current sensing.
- Designed for automotive applications with extended temperature ratings and high reliability standards.
- Includes comprehensive protection features such as overcurrent protection, thermal shutdown, and undervoltage lockout.
Applications
- Automotive DC motor control systems
- Solenoid drivers in vehicle actuation circuits
- General purpose half-bridge power switching applications
Procurement Notes
Verify the exact suffix and package variant against the manufacturer's latest datasheet before ordering. Confirm that the 24-pin TSSOP footprint matches your PCB design. Ensure compliance with automotive quality standards required for your specific application environment. Check for any recent lifecycle status updates or obsolescence notices from Allegro MicroSystems.
Selection Notes
Select this component when a compact, integrated solution for driving half-bridge configurations is required. It is suitable for applications needing integrated current sensing without external amplifiers. Consider the thermal performance of the TSSOP package and ensure adequate PCB copper area for heat dissipation. Verify input logic levels are compatible with your microcontroller or control interface.
Part Context
This part belongs to Allegro MicroSystems' portfolio of automotive-grade power management ICs. It is specifically engineered for durability in electric and hybrid vehicles. The integration of the sense amplifier reduces bill-of-materials count compared to discrete solutions. It complements other gate drivers in the series offering varying current capabilities and packaging options.
Replacement Considerations
Check for direct pin-to-pin replacements within the same Allegro family. Verify if alternative parts offer improved thermal characteristics or different current ratings. Ensure substitute components meet the same automotive qualification standards. Review functional compatibility regarding drive strength and protection thresholds.
