Description
The PT7M6518-6550 is a family of small, low-power,
voltage-monitoring circuits with adjustable delay time
capability. PT7M65xx series features a highly accurate
under voltage detector with hysteresis and an
externally programmable time delay generator. This
combination of features prevents erratic system reset
operation.
PT7M65xx series provide external capacitor to adjust
for set up delay time.
All series operate from a 1.2V to 5.5V supply voltage
and are fully specified over the -40° to +85°

operating temperature range. This family is available
in ultra-small 4-pin UDFN (1.6mm x 1.6mm) and
SC70-4 and SOT23-5 packages.
