The SA59202 is a gas gauge IC for multi-cell batteries in handheld and portable equipment. It senses battery terminal voltage, charging/discharging current by an internal 12-bit ADC. The wide input voltage range allows user with multi-cell batteries up to 25V. An accurate coulomb counter integrates current through a sense resistor between the battery’s positive terminal and the load/charger. The test results are stored in internal registers which is accessible via the I2C Interface.
The SA59202 has programmable high and low thresholds for all measured quantities. If a programmed threshold is exceeded, the device will communicate an alert using either the alert response procedure or by setting a flag in the internal status register.
