3.30 BATTERY VOLTAGE REGULATION, CHARGE VOLTAGE
3.31 LDO MODE OPERATION
TPS658620
Advanced Power Management Unit
SLVS993 – OCTOBER 2009
www.ti.com
The ISET resistor will always set the maximum charge current if the AC input is selected. When the USB
input is selected the maximum charge current will be defined by the USB input current limit and the
programmed charge current. If the USB input current limit is lower than the IO(BAT) value, the battery switch
will be set in the dropout region and the charge current will be defined by the input current limit value and
system load, as shown in Figure 3-10.
Figure 3-10. USB Supplement Mode
The Voltage regulation feedback is implemented by sensing the BAT pin voltage, which is connected to
the positive side of the battery pack. The TPS658620 monitors the battery-pack voltage between the BAT
and AGND1 pins. When the battery voltage rises to the VO(BATREG) threshold, the voltage regulation phase
begins and the charging current tapers down.
The charging voltage can be selected via I2C, with bits VCHG<1:0> (register VCHG1) and RSVD4B4
(register PPATH1, 0x4C)
The LDO mode makes it possible to run critical subsystems connected directly to the battery node (BAT
pin) when the battery is removed and the end equipment is powered by the AC or USB input.
The SM2 voltage must be programmed by the host via register SUPPLYV2 control bits VSM2<4:0> to a
value 100mv above the programmed charge voltage before the LDO mode is enabled, and it should be
left at that value while LDO mode is in use. The SM2 voltage can be set to any other value after the LDO
mode is disabled.
The charger LDO Mode operation is enabled when termination is disabled (TERMOFF bit is 1 in CHG1)
and thermistor removal detection is ignored (setting TSBYP bit to 1 in CHG2).
When the LDO mode is set, termination is disabled, all safety timers are held in reset, and the battery
discharge switch is disabled. The BAT pin voltage will regulate to VO(BATREG) when all the following
conditions are true: the charger is enabled (VIN_CHG > VO(BATREG)) and input power is present (AC or
USB input power detected). Under these conditions the BAT pin voltage will be regulated to the charge
voltage VO(BATREG) if the charger current loops are not active.
The charger current limit loop will still be enabled, and the current that can be supplied by the BAT pin in
LDO mode will be dependent on the BAT pin voltage, as shown in Table 3-10.
