The XTR116UA is an advanced monitoring circuit from Texas Instruments. It is designed to sense battery voltage and current levels on rechargeable lead acid batteries, used in applications for battery-powered devices. The device utilizes a shunt resistor and a precise amplifier to measure current and a precision voltage divider to measure voltage levels. It also can detect short circuit conditions and is fully protected against reverse battery connections. The XTR116UA can be used as a battery protection circuit, a total/partial discharge detector, a low-charge warning indicator, and a fuel gauge to track the accurate state of charge of the battery.
