TEA1102 - Fast charge ICs for NiCd, NiMH, SLA and LiIon

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. 

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

• 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.
