TEA1102 Overview
plastic dual in-line package; 20 leads (300 mil) TEA1102; TEA1102TS GENERAL DESCRIPTION The TEA1102x are fast charge ICs which are able fast charge NiCd and NiMH, SLA and Lilon batteries.
TEA1102 Key Features
- Safe and fast charging of Nickel Cadmium (NiCd), Nickel Metal Hydride (NiMH), Lithium Ion (LiIon), and Sealed Lead Acid
- Three charge states for NiCd or NiMH; fast, top-off and trickle or voltage regulation (optional)
- Two charge states for LiIon or SLA; current and voltage limited
- Adjustable fast charge current [0.5CA to 5CA nominal (CA = Capacity Amperes)]
- DC top-off and pulsating trickle charge current (NiCd and NiMH)
- Temperature dependent ∆T/∆t battery full detection
- Automatic switch-over to accurate peak voltage detection (-1⁄4%) if no NTC is applied
- Possibility to use both ∆T/∆t and peak voltage detection as main fast charge termination
- Support of inhibit during all charging states
- Manual refresh with regulated adjustable discharge current (NiCd and NiMH)
