Overview

The BQ25120AEVM is a comprehensive evaluation module designed to demonstrate the capabilities of the BQ25120A, a highly integrated battery management IC featuring a 700nA low quiescent current. This module enables engineers to test linear charging, a regulated buck converter, and a load switch/LDO in a single compact design. It is specifically optimized for small-form-factor applications that require extremely long standby times from low-capacity Li-ion batteries.

Why Choose This Part

The BQ25120AEVM showcases an industry-leading 700nA quiescent current, which significantly extends battery life in always-on applications. Its high level of integration combines a charger, buck converter, and supervisor into a single package, reducing total PCB area and BOM cost. The I2C interface allows for flexible software control over charge parameters and output voltages.

Applications

Wearable Health Monitors
Ideal for fitness trackers and medical patches where ultra-low Iq is critical for multi-day operation between charges.
Hearables
Supports the small battery capacities found in TWS earbuds and Bluetooth headsets with precise charge termination.
Smart Watches
Provides the high efficiency and small footprint required for space-constrained consumer wearables with multiple power rails.
IoT Sensor Nodes
Manages power for remote sensors that spend the majority of their time in deep sleep modes.

Getting Started

Connect the EVM to a PC using a USB2ANY interface adapter to utilize the TI Evaluation Software for real-time configuration. Users should provide a single-cell Li-ion battery or a battery simulator to the BAT terminal and a 5V supply to the VIN terminal. The board includes jumpers to configure hardware-controlled parameters like current limits and buck enable.
