Overview

The BQ24075EVM-656 is a complete evaluation module for the BQ24075, a single-cell Li-Ion battery charger and power path management IC. It demonstrates how to manage power from a USB port or AC adapter while simultaneously charging a battery and powering a system load. The board supports input voltages up to 26V with an integrated 6.6V overvoltage protection circuit.

Why Choose This Part

The module features dynamic power path management (DPPM) which allows the system to remain powered even when the battery is deeply discharged or removed. It provides high input voltage protection up to 26V and allows for independent programming of charge and termination currents.

Applications

Portable Medical Devices
Managing power path transition between external wall adapters and internal Li-Ion batteries for continuous operation.
Handheld Terminals
Utilizing the 1.5A maximum output current to power high-drain wireless modules while charging the battery.
Smart Home Hubs
Implementing a robust charging solution with integrated safety timers and system-level power prioritization.

Getting Started

Connect a 5V power source to the input headers and a single-cell Li-Ion/Li-Pol battery to the BAT terminals. Use the onboard jumpers to configure the charge current and EN/SYSOFF pins to test various power states. Monitor the CHG and PGOOD LED indicators to verify charging status and input power availability.

Also Consider

BQ24072EVM TITexas Instruments - Consider this if you require a different VOUT regulation logic where VOUT tracks the battery voltage plus a small offset.
