LP873248RHDRQ1

Overview

The LP873248RHDRQ1 is an automotive-grade PMIC featuring two 2-A synchronous buck converters and two linear regulators. It operates with an input voltage range of 2.8 V to 5.5 V. The buck outputs provide adjustable voltages from 700 mV to 3.36 V, while the LDOs support up to 300 mA. Integrated features include I2C control, programmable sequencing, spread-spectrum clocking, and thermal protection. The device is housed in a 28-pin VQFN package and meets AEC-Q100 standards for operation between -40°C and +125°C.

Feature Summary

Integrates dual high-current buck converters and dual low-dropout linear regulators for comprehensive power management.
Supports programmable start-up and shutdown delays with precise power sequencing capabilities.
Includes spread-spectrum clock generation to minimize electromagnetic interference during switching operations.

Applications

TDA3x processor power supply systems
Automotive infotainment units
Advanced driver-assistance systems (ADAS)

Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm exact output configurations and pin assignments. Ensure the component meets AEC-Q100 grade requirements for your target automotive application environment. Cross-reference datasheet revisions to validate feature availability before finalizing procurement specifications.

Selection Notes

Select this component when designing for TDA3x processors requiring integrated buck and LDO solutions. Consider the 28-pin VQFN package constraints for PCB layout. Evaluate the need for spread-spectrum functionality to meet EMI compliance targets in sensitive automotive environments.

Part Context

This part belongs to the LP8732xx-Q1 family of specialized PMICs designed for automotive applications. It shares architectural similarities with other devices in the series but offers specific current ratings and output configurations tailored for complex processor power domains.
