A3924KLVTR-T

Overview

The A3924KLVTR-T is an automotive full-bridge MOSFET driver with dual sense amplifiers, designed for brushed DC motor control. It operates within a supply voltage range of 5.5 V to 50 V and features internal charge pumps generating 8 V and 13 V outputs. The device supports a wide operating temperature range from -40°C to +150°C TJ. It is housed in a TSSOP-38 package with exposed pad for surface mount installation.

Feature Summary

Integrated full-bridge MOSFET driver architecture with dual current sense amplifiers
Automotive-grade reliability suitable for harsh environmental conditions
Internal charge pump circuitry providing optimized gate drive voltages

Applications

Automotive brushed DC motor control systems
Active cooling fans and blowers
Window lift actuators
Seat adjustment motors

Procurement Notes

Verify the complete part number including suffixes against official Allegro MicroSystems documentation to ensure correct packaging and temperature grade. Confirm RoHS compliance status through the manufacturer's latest datasheet or certification documents before finalizing procurement specifications.

Selection Notes

Select this component when designing automotive brushed DC motor applications requiring integrated sensing and high thermal performance. Ensure the system voltage remains within the 5.5 V to 50 V operational window. Verify that the TSSOP-38 package footprint matches the PCB layout requirements and thermal dissipation needs.

Part Context

This part belongs to the A3924 series of automotive motor drivers. It is distinct from evaluation tools like APEK3924KLV-01-T and other driver families such as A3922 or A4939. The KLV suffix indicates specific packaging and temperature characteristics defined by the manufacturer.
