Overview

The BQ24074RGTR is a highly integrated Li-Ion linear charger and system power path management IC designed for space-constrained portable applications. It features a 28V input rating with overvoltage protection and supports autonomous power path control, allowing the system to be powered while the battery is simultaneously being charged.

Why Choose This Part

This IC excels in power management by utilizing Integrated Dynamic Power Path Management (DPPM) to prioritize system loads over battery charging. It provides a high level of safety with an input rating up to 28V, integrated timers, and a functional safety-capable design for high-reliability systems.

Applications

Portable Medical Devices
Ideal for handheld diagnostic tools requiring IEC 62368-1 certification and reliable NTC-based thermal monitoring.
Smart Home Sensors
Suitable for battery-powered IoT devices that need to manage power between a USB source and a single-cell Li-Ion battery.
Industrial Handhelds
Used in rugged mobile terminals where programmable charge currents up to 1.5A and robust fault protection are required.
