Overview

The BQ24075QRGTRQ1 is an AEC-Q100 qualified integrated Li-Ion linear charger and system power path management IC designed for space-constrained portable applications. It allows for simultaneous battery charging and system powering from either a USB port or an AC adapter, supporting charge currents up to 1.5A.

Why Choose This Part

The integrated dynamic power path management (DPPM) allows the system to power the load even with a deeply discharged or missing battery. It features an automotive-qualified design with input overvoltage protection up to 28V and thermal regulation to maximize charge rate without overheating.

Applications

Automotive Infotainment Systems
Managing power for head units or secondary displays that require USB-based charging and battery backup.
Emergency Call (eCall) Modules
Reliable battery charging and power path management for backup power systems in vehicle safety modules.
Portable Telematics Units
Ensuring continuous operation while switching between external power sources and internal Li-Ion batteries.

Getting Started

Engineers can evaluate this part using the BQ24075EVM evaluation module to test power path transitions and charging profiles. When designing the PCB, ensure short, wide traces for the VIN, OUT, and BAT pins to minimize voltage drops and provide adequate thermal via stitching under the QFN package pad.
