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°C to +85°C 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.
