BQ27541EVM

BQ27541EVM is an evaluation module (EVM) designed for use in evaluating the performance of Texas Instruments BQ27541-G1 Li-ion battery fuel gauges for single cell Li-ion/Li-polymer battery packs. This EVM is a single-cell version of the BQ27541 device. It is intended to be a flexible source of power and a gauge of fuel level for portable device applications.

The EVM is comprised of a BQ27541 IC, a buck hydrogen gas sensor, a 100 ohm series resistor, and additional components designed to replicate a single cell Li-ion/Li-polymer battery stack. The EVM also includes a USB connector to allow easy connection to a computer. The user can easily program the EVM to measure features such as remaining capacity, health, and state of charge (SOC) on the battery stack.

The BQ27541EVM implements a multistage fuel gauge architecture to accurately measure a variety of fuel levels for single cell Li-ion/Li-polymer battery packs. The primary purpose of the EVM is to measure remaining battery capacity and health, but it can also be used to measure SOC. The EVM includes an on-board hydrogen gas sensor which can detect any dangerous gas levels that may occur during charging or discharging. The gas sensor can be calibrated or disabled if not desired.

In addition to the primary features mentioned above, the BQ27541EVM also includes a power switch and indicators to indicate the status of the device, as well as switches to control various other features such as deep sleep/hibernate modes. The user can easily configure the EVM using the USB connection to the computer and the EZ-Link software provided.

The BQ27541EVM is a versatile evaluation module for Li-ion/Li-polymer battery stacks and can provide a broad range of useful information about the battery pack’s performance. The EVM provides a comprehensive level of information that is valuable both to product designers and knowledgeable end-users. The user can easily use the BQ27541EVM to measure the remaining capacity, health, and SOC of the battery stack. Additionally, the hydrogen gas sensor is an important addition to the EVM which adds additional safety and allows the user to monitor hazardous gases in the vicinity of the battery stack.

The BQ27541EVM is a convenient and cost-effective solution for anyone looking to accurately measure the performance of Li-ion/Li-polymer battery stacks. It is designed as an all-in-one device, and does not require any additional hardware or components to function. All necessary components are provided on-board, and the user has the additional convenience of being able to easily program the device with the EZ-Link software.
