Figure 22. Typical Operating Circuit TPS60212 With Low-Battery Comparator
The current losses through the resistive divider used to set the low-battery threshold can be avoided if an
additional MOSFET (like BSS138) is used in series to the resistors. This switch is controlled using the SNOOZE
signal. When the SNOOZE-signal is taken high, the device is programmed into normal operating mode, the
switch will turn on and the resistive divider draws current to set the LBI threshold voltage. When SNOOZE is
taken low, the device is programmed into snooze mode during which the low-battery comparator is disabled.
In addition, the resistive divider R1/R2 is disconnected from GND and therefore draws no current from the
battery. A typical schematic for this circuit is shown in Figure 22.
