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 (14%) 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
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.
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.
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.
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.
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.
