Working Principles

The DS2762BE+025 operates by continuously monitoring the voltage and current of the battery connected to its VBAT and VSS pins. It uses an internal ADC (Analog-to-Digital Converter) to convert the analog signals into digital values. These values are then processed by an internal microcontroller, which performs various calculations and comparisons to determine the battery's state.

The device can be programmed to trigger an alert when certain conditions are met, such as low battery voltage or high current draw. The alert is indicated through the ALERT pin, which can be connected to an external circuit for further action.

Detailed Application Field Plans

  1. Portable Electronics: The DS2762BE+025 can be used in smartphones, tablets, and other portable devices to monitor battery health and provide protection against overvoltage and overcurrent conditions.
