Preliminary specification  
Fast charge ICs for NiCd and NiMH  
batteries  
TEA1103; TEA1103T;  
TEA1103TS  
FEATURES  
GENERAL DESCRIPTION  
• Safe and fast charging of Nickel Cadmium (NiCd) and  
Nickel Metal Hydride (NiMH) batteries  
The TEA1103x are fast charge ICs which are able to fast  
charge NiCd and NiMH batteries.  
• Pin compatible with the TEA1102x, fast charge ICs for  
LiIon, SLA, 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 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.  
• 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)  
Several LEDs, as well as a buzzer, can be connected to  
the TEA1103x for indicating battery insertion, charge  
states, battery full condition and protection mode.  
• Temperature dependent ∆T/∆t battery full detection  
• Automatic switch-over to accurate peak voltage  
detection (−1⁄4%) if no NTC is applied  
The TEA1103x are contained in a 20-pin package and are  
manufactured in a BiCMOS process, essentially for  
integrating the complex mix of requirements in a single  
chip solution. Only a few external low cost components are  
required in order to build a state of the art charger.  
• 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)  
The TEA1103x are pin compatible with the TEA1102x, fast  
charge ICs for LiIon, SLA, NiCd and NiMH batteries.  
• 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  
• Single, dual and separate LED outputs for indication of  
charge status state  
• Minimum and maximum temperature protection  
• Time-out protection  
• Short-circuit battery voltage protection  
• Can be applied with few low-cost external components.
