TEA1104 Overview
The TEA1104 is manufactured in a BiCMOS process intended to be used as a battery monitor circuit in charge systems for NiCd and NiMH batteries. It is especially designed for cost effective pact consumer applications. The circuit is able to detect fully charged batteries by currentless battery voltage sensing.
TEA1104 Key Features
- Accurate detection of fully charged batteries by currentless peak voltage sensing
- Switch-over from fast to safe trickle charge current at battery full detection
- Fast charge termination back-up by maximum time and maximum temperature detection
- Several trickle charge drive possibilities for mains isolated and non-mains isolated systems
- Battery checking to protect against short-circuited and open batteries
- Battery monitor allows recharging of different battery packs in the same charger
- Dual LED indicator provision
- External regulator not required because of large input voltage range
- Few low cost external ponents required
