The battery voltage is monitored by a comparator via an external resistor divider. When the voltage at the LSENSE input drops below the internal reference voltage the RSTSENSE output pulls low. The output remains low until the battery is replaced, or recharged above a second higher trip-point, set at HSENSE. A second voltage can be monitored at V . The independent RESET output pulls low when the DD voltageatV dropsbelowthefixedthresholdvoltage.BecausetheTPS3806outputs are open-drain MOSFETs, DD mostapplicationsmayrequireapull-upresistor.
