DETAILED DESCRIPTION (continued)
Figure 28. TS Pin Configuration
Figure 29. TS Pin Threshold
On power up, if the battery voltage is below the V
(LOWV)
threshold, the TPS65010 applies a precharge current,
I
(PRECHG)
, to the battery. This feature revives deeply discharged cells. The charge current during this phase is one
tenth of the value in current regulation phase which is set with I
O(out)
= KSET

V
(SET)
/R
(SET)
. The load current in
preconditioning phase must be lower than I
(PRECHG)
and must allow the battery voltage to rise above V
(LOWV)
within t
(Prechg)
. VBAT_A is the sense pin to the voltage comparator for the battery voltage. This allows a power on
sense measurement if the VBAT_A and VBAT_B pins are connected together at the battery.
The TPS65010 activates a safety timer, t
(PRECHG)
, during the conditioning phase. If V
(LOWV)
threshold is not
reached within the timer period, the TPS65010 turns off the charger and indicates the fault condition in the
CHGSTATUS register. In the case of a fault condition, the TPS65010 reduces the current to I
(DETECT)
. I
(DETECT)
is
used to detect a battery replacement condition. Fault condition is cleared by POR or battery replacement or via
the serial interface.
TPS65010 offers on-chip current regulation. When charging from an ac adapter, a resistor connected between
the ISET1 and AGND pins determines the charge rate. A maximum of 1-A charger current from the ac adapter is
allowed. When charging from a USB port either a 100-mA or 500-mA charge rate can be selected via the serial
interface, default is 100 mA max. Two bits are available in the CHGCONFIG register in the serial interface to
reduce the charge current in 25% steps. These only influence charging from the ac input and may be of use if
charging is often suspended due to excessive junction temperature in the TPS65010 (e.g., at high ac input
voltages) and low battery voltages.
