LP87322ERHDTQ1

Overview

The LP87322ERHDTQ1 is a Texas Instruments automotive power management IC designed for camera modules. It integrates two high-current buck converters and two linear regulators within a 28-pin VQFN package. The device supports an input voltage range of 2.8 V to 5.5 V, with buck outputs adjustable from 0.7 V to 3.6 V at up to 2 A each. It operates between -40°C and +125°C and holds AEC-Q100 qualification.

Feature Summary

Integrates dual high-current buck converters and dual low-dropout linear regulators in a single compact package.
Features automatic PWM/PFM mode switching to maintain high efficiency across varying load conditions.
Supports remote voltage sensing to compensate for IR drops between the regulator output and the load point.
Includes programmable switching frequency synchronization to external clocks for interference minimization.

Applications

Automotive camera module power distribution
TDA3x processor power supply systems
J6 entry-level processor platforms

Procurement Notes

Verify the complete part number including suffixes such as RHDTQ1 against official Texas Instruments documentation to ensure correct package type and temperature rating. Confirm AEC-Q100 compliance requirements match the specific automotive application standards before procurement.

Selection Notes

Select this component when designing automotive camera systems requiring integrated buck and LDO regulation. Ensure the design utilizes the 28-VQFN footprint and accounts for the 2.8 V to 5.5 V input range. Verify thermal performance under maximum load conditions given the 2 A per buck converter capability.

Part Context

This device belongs to the LP8732 family of automotive PMICs. It shares functional similarities with parts like the LP873200RHDRQ1 but offers distinct integration levels. The LP8732 series targets high-performance automotive processing and imaging applications requiring efficient multi-rail power delivery.

Replacement Considerations

LP873200RHDRQ1 serves as a parameter-equivalent alternative for certain dual-buck configurations. Verify pin compatibility and output current specifications before substitution.
