General Instructions
TEA1104 is manufactured in BiCMOS process and intended as a rechargeable battery monitoring circuit for NiCd and NiMH battery systems. This is especially designed for cost-effective compact consumer applications. The circuit is able to detect a fully charged battery with currentless battery voltage detection. Multiple output driver functions can be used to control (reduce) the dripping charge current to maintain the full maximum life expectancy of the battery. Full battery detection is provided by two independent backup mechanisms, making the system fail-safe for maximum time to maximum temperature.
