TEA1103TS - NXP

TEA1103TS Fast charger

plastic dual in-line package; 20 leads (300 mil) TEA1103; TEA1103T; TEA1103TS GENERAL DESCRIPTION The TEA1103x are fast charge ICs which are able to fast charge NiCd and NiMH batteries. 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 switc.

Features

• Safe and fast charging of Nickel Cadmium (NiCd) and Nickel Metal Hydride (NiMH) batteries
• Pin compatible with 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/∆.
