Philips Semiconductors  
Preliminary specification  
Fast charge ICs for NiCd, NiMH, SLA and  
LiIon  
TEA1102; TEA1102T;  
TEA1102TS  
FEATURES  
GENERAL DESCRIPTION  
• Safe and fast charging of Nickel Cadmium (NiCd),  
Nickel Metal Hydride (NiMH), Lithium Ion (LiIon), and  
Sealed Lead Acid (SLA) batteries  
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.  
• 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  
Charging Lilon and SLA batteries is completely different.  
When the batteries reach their maximum voltage  
(adjustable), the TEA1102x switches over from current  
regulation to voltage regulation. After a defined time  
period, which is dependent on battery capacity and charge  
current, charge is terminated. Due to small self discharge  
rates of Lilon and SLA batteries, trickle charge can be  
omitted.  
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  
Several LEDs, as well as a buzzer, can be connected to  
the TEA1102x for indicating battery insertion, charge  
states, battery full condition and protection mode.  
• Manual refresh with regulated adjustable discharge  
current (NiCd and NiMH)  
• Voltage regulation in the event of no battery  
The TEA1102x 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.  
• 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.
