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 automatically switches over from∆T/∆t to peak voltage detection if the thermistor fails or is not present. The∆T/∆t
detection sensitivity is temperature dependent, thus avoiding false charge termination. Three charge states can be distinguished; fast, top-off and trickle.
