TEA1102 - NXP

TEA1102 Fast charger

plastic dual in-line package; 20 leads (300 mil) TEA1102; TEA1102T; TEA1102TS GENERAL DESCRIPTION The TEA1102x are fast charge ICs which are able fast charge NiCd and NiMH, SLA and Lilon 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 TEA1102x automa.

Features

• Safe and fast charging of Nickel Cadmium (NiCd), Nickel Metal Hydride (NiMH), Lithium Ion (LiIon), and Sealed Lead Acid (SLA) batteries
• 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
• Possibil.
