LP87332DRHDTQ1

Overview

The LP87332DRHDTQ1 is an automotive-grade PMIC from the LP8733 series, housed in a 28-VQFN package. It integrates four output regulators: two high-current buck converters and two low-dropout linear regulators (LDOs). The buck outputs support up to 3 A with adjustable voltages from 0.7 V to 3.36 V. The LDO outputs provide up to 300 mA with adjustable voltages from 0.8 V to 3.3 V. Operating from a 2.5 V to 5.5 V supply, it features a 2 MHz switching frequency and functions within a -40°C to +125°C temperature range.

Feature Summary

• Integrates dual 3-A buck converters and dual 300-mA LDOs for multi-rail power distribution
• Supports surface-mount installation with wettable flanks for enhanced inspection reliability
• Certified to AEC-Q100 standards for automotive application suitability

Applications

• Automotive infotainment systems requiring multiple regulated voltage rails
• Digital cockpit modules needing combined switching and linear regulation
• ADAS sensor interfaces utilizing automotive-qualified power management ICs

Procurement Notes

Verify the specific suffix DRHDTQ1 against the official Texas Instruments datasheet to confirm pinout and electrical characteristics. Ensure the component meets AEC-Q100 requirements for your target automotive environment. Cross-reference the 28-VQFN footprint dimensions during PCB layout to prevent assembly errors.

Selection Notes

Select this device when a single solution is needed for both high-current switching and precision linear regulation. The integrated topology reduces component count compared to discrete designs. Verify that the required output currents do not exceed the 3 A limit for buck channels or 300 mA for LDO channels.

Part Context

This part belongs to the LP8733 family of specialized PMICs designed for complex power architectures. It complements other variants like the LP87334 by offering mixed regulator topologies. The Q1 suffix indicates qualification for automotive environments, distinguishing it from standard commercial grade parts.

Replacement Considerations

LP87332BRHDTQ1 is a parameter-equivalent alternative within the same family.
