NXP Semiconductors TEA1103

the TEA1102x, fast charge ICs for LiIon, SLA, NiCd and NiMH batteries • Three charge states for NiCd or NiMH; fast, top-off and trickle or voltage regulation (optional) • 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 •... The main fast charge termination for NiCd and NiMH batteries are ∆T/∆t and peak voltage detection, both of which are well proven techniques. The TEA1103x automatically switches over from ∆T/∆t to peak voltage detection if the thermistor fails or is not present.
