TEA1104
Description
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.
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
- Portable telephone
- Portable puter
