NXP Semiconductors TEA1102
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.| Part No. | TEA1102 |

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
● 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)
● Voltage regulation in the event of no battery
● Support of battery voltage based charge indication and buzzer signalling at battery insertion, end of refresh and at full detection
● S...
