Overview

The BQ24074EVM is a complete evaluation module for the BQ24074, a linear Li-Ion battery charger and system power path management IC. It provides a platform to test features like dynamic power path management, adjustable charge current up to 1.5A, and input current limiting from a USB or AC adapter source.

Why Choose This Part

The board features integrated power path management which allows the system to remain powered even with a deeply discharged or missing battery. It includes convenient jumpers and test points for real-time monitoring of input current, charge status, and battery voltage levels.

Applications

Handheld Device Prototyping

Rapidly test power management for portable scanners, medical meters, or industrial handsets requiring simultaneous battery charging and system operation.

USB-Powered Systems

Evaluate the IC performance when transitioning between USB power and battery power while maintaining a stable system voltage.

Battery Charging Optimization

Fine-tune charge parameters such as safety timers, termination current, and thermal regulation for specific Li-Ion cell chemistries.

Getting Started

Connect a 5V power source to the J1 input and a single-cell Li-Ion battery to the J2 header. Use the onboard jumpers to configure the EN1 and EN2 pins for different input current limits and monitor the CHG and PGOOD LEDs for status indication.
