NCV308SN180T1G

The NCV308 microprocessor supervisory product family is designed to assert a RESET signal when either the SENSE pin voltage drops below VIT or the Manual Reset input (MR) is driven low. The RESET output remains asserted for a programmable delay time after both MR and SENSE voltages return above the respective thresholds. A broad range of voltage threshold and reset delay time options are available, allowing NCV308 series to be used in a wide range of applications. Reset threshold voltages can be factory−set from 1.67 V to 4.65 V while the NCV308SNADJ can be used for any voltage above 0.405 V using an external resistor divider.
