4.6
When the input voltage (V
threshold, the V
ensure that, if the voltage is not adequate to operate
the MCP1630/V, the main power supply switch will be
held in the off state. When the UVLO threshold is
exceeded, there is some hysteresis in the input voltage
prior to the UVLO off threshold being reached. The
typical hysteresis is 75 mV. Typically, the MCP1630 will
not start operating until the input voltage at V
between 3.0V and 3.1V.

junction temperature is above the thermal shutdown
threshold. There is an internal 100 k pull-down resis-
tor connected from V
