Evaluation and demonstration boards and kits are primarily tools for engineers and designers for the study and development of their product ideas or concepts. The BQ25040EVM is an evaluation module for the bq25040, a single-cell, single-stage Li-ion linear battery charger IC. This module is a complete fixed-frequency linear charger solution. The IC supports a wide input voltage range from 2.7 V to 20 V and a wide output current range from 30 mA to 4 A. It is suitable for different kinds of applications from consumer to automotive. This article will discuss the application field and working principle of the BQ25040EVM.
The BQ25040EVM has a wide range of applications in a variety of industries. It can be used to develop battery-powered equipment such as wearable, remote sensing and IoT, consumer electronics, and medical. It is also suitable for the automotive market, especially for automobiles that use Li-ion battery packs. Other applications include UPS systems, back-up power solutions, and industrial power supplies. The EVM module also has the capability to handle Digital Signal Processor applications in Renesas R-Car series.
The BQ25040EVM works in a constant frequency linear mode and in a pulse-width modulation mode. In constant frequency linear mode, the controller IC switches between two clock frequencies, which are set by external frequency selection circuits. In pulse-width modulation mode, the IC switches between two different levels of output duty cycle, which are set by external PWM selection circuits. The two modes operate simultaneously and can be selected through a jumper on the board. A current sense resistor is also included on the board to sense the load current.
The BQ25040EVMs working principle is based on the following key elements:
- The current sense resistor is used to sense the load current and output the sensed current to the controller IC.
- The frequency selection circuits are used to select the output clock frequency. This is a feature of the IC that allows for greater flexibility in system design.
- The PWM selection circuits are used to set the output duty cycle of the controller IC. The output duty cycle is used to adjust the charge current of the battery.
To use the BQ25040EVM, the user must connect the IC to a battery and the input power source. The output from the IC can be measured using an oscilloscope or a digital multimeter. The output voltage and current can be adjusted by adjusting the voltage and current settings on the board. The user can also monitor and control the charging process through the onboard graphical user interface (GUI).
The BQ25040EVM is a powerful and versatile evaluation module that is suitable for a wide range of applications. It is an ideal tool for engineers and designers to study and develop various product ideas or concepts. It can be used to develop battery-powered products, consumer electronics, automotive applications, UPS systems, back-up power solutions, and industrial power supplies. The BQ25040EVM is a great tool for testing and evaluating different applications.
