MCP1630/MCP1630V

Undervoltage Lockout (UVLO)
4.7
Overtemperature Protection
When the input voltage (V IN ) is less than the UVLO
threshold, the V EXT is held in the low state. This will
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 IN is
between 3.0V and 3.1V.
? 2005 Microchip Technology Inc.
To protect the V EXT output if shorted to V IN or GND, the
MCP1630/V V EXT output will be high-impedance if the
junction temperature is above the thermal shutdown
threshold. There is an internal 100 k Ω pull-down resis-
tor connected from V EXT to ground to provide some
pull-down during overtemperature conditions. The
protection is set to 150°C (typ.), with a hysteresis of
18°C.
