POWER SUPPLY MANAGEMENT IC AND
Li-Ion BATTERY CHARGE CONTROL
SLVS280 – MARCH 2001
22
POST OFFICE BOX 655303
DALLAS, TEXAS 75265
APPLICATION INFORMATION
control register—FCR1 (1BH)
BIT
NAME
DESCRIPTION
7
CHGSTR
Set this bit to 1 to start the charger operation. This bit is cleared if the charger is terminated. (Refer to status
register table below for terminated conditions)
6
ADC
ENABLE
Set this bit to 1 to enable ADC operation, 0 to stop.
5
ADC
Function
Set this bit to 1 to have ADC operate continuously. Set to 0 to have ADC to operate one cycle only.
4
ADBV
Set this bit to 1 to enable the VBAT input channel to ADC. 0: disable.
3
VTS
Set this bit to 1 to enable the VTS input channel to ADC. 0: disable.
2
ADCIN1
Set this bit to 1 to enable the ADCIN1 input channel.
1
ADCIN2
Set this bit to 1 to enable the ADCIN2 input channel.
0
IRQ
Status of IRQ pin (refer to IRQ operation section).
ADC has four input channels (ADBV, VTS, ADCIN1, ADCIN2). Each channel can be enabled or disabled
individually. The selected channel must be enabled before ADC FUNCTION and ADC ENABLE bits are
enabled, the channel is included in the ADC operation.
IRQ control/status
TWL2213 uses the IRQ signal to inform the external controller about the exception condition of the VCHG input
and the charger status. Bit0 reflects the state of the IRQ signal. IRQ occurs in the following five conditions:
1.
VCHG returns to operating range from non_operating range.
2.
VCHG goes out of range from operating range.
3.
Battery error—occurs only during the charging cycle.
4.
Battery temperature out of range—occurs only during the charging cycle. The charger is suspended
temporarily. IRQ is cleared when the temperature returns to normal and the charger resumes automatically.
5.
Charge complete.
The controller must clear the IRQ signal by writing 0 to Bit0 in the interrupt service routine, except in the VBOT
condition. The controller may miss the next interrupt if it fails to write the 0. In VBOT condition, TWL2213 clears
the IRQ when the condition goes away.
status register description—SR (1CH)
SR shows the status of the charger. The external controller reads the SR to track the state of the charging
condition.
