Preliminary specification
TEA1102; TEA1102T;
TEA1102TS
After the ‘fill-up’ period the charge current is not regulated,
which means that the output drivers AO and PWM are
fixed to zero. When the battery voltage becomes less than
3 V for Lilon and 1.5 V for SLA, the IC enters the fast
charge mode again.
FUNCTIONAL DESCRIPTION
Control logic
The main function of the control logic is to support the
communication between several blocks. It also controls
the charge method, initialization and battery full detection.
The block diagram of the TEA1102x is illustrated in Fig.1.
Conditioning charge method and initializations
At system switch-on, or at battery insertion, the control
logic sets the initialization mode in the timer block. After
the initialization time the timer program pins can be used
to indicate the charging state using several LEDs.
The charge method is defined at the same time by the
following methods:
If the FCT pin is 0 or 1.25 V, indicating that SLA or LiIon
batteries have to be charged, the battery will be charged
by limit current and limit voltage regulation. Without
identification (FCT pin floating), the system will charge
the battery according to the charge characteristic of
NiCd and NiMH batteries.
The standby charge method (NiCd and NiMH), trickle
charge or voltage regulation, is defined by the input pin
Vstb. By biasing this voltage with a set voltage, the output
voltage will be regulated to the Vstb set voltage. If this pin
is connected to VS, or no NTC is connected the system
applies trickle charge.
If pin RFSH is connected to ground by depressing the
switch, the TEA1102x discharges the battery via an
external transistor connected to pin RFSH. The discharge
current is regulated with respect to the external (charge)
sense resistor (Rsense). End-of-discharge is reached when
the battery is discharged to 1 V per cell. Refreshing the
battery can only be activated during charging of NiCd and
NiMH batteries. When charging LiIon and SLA batteries,
discharge before charge is disabled.
The inhibit mode has the main priority. This mode is
activated when the Vstb input pin is connected to ground.
Inhibit can be activated at any charge/discharge state,
whereby the output control signals will be zero, all LEDs
will be disabled and the charger timings will be set on hold.
Table 1 gives an operational summary.

1. Where X = don’t care.
2. Not low means floating or high.
3. The NTC voltage has been to be less than 3.3 V, which indicates the presence of an NTC.
4. The NTC voltage is outside the window for NTC detection.
5. Vstb has to be floating or set to a battery regulating voltage in accordance with the specification.
