ET3895中文资料ADJ Voltage Monitor数据手册ETEK规格书

描述 Description

The ET3895 low power voltage detector provides monitoring of battery, power-supply, and regulated system voltages. The devices is a very small supervisory circuits that monitor voltages greater than 500mV with a 0.25% (typical) threshold accuracy and offer adjustable delay time using external capacitors.The ET3895 also has a logic enable pin EN to power on and off the output. when the input voltage pin (IN) rises above the threshold, and the EN pin is high, then the output pin OUT goes high after the capacitor-adjustable delay time. When IN falls below the threshold or EN is low, then OUT goes low.The ET3895 is available in ultra-small µDFN6 package and is fully specified the temperature range of TA = -40°C to 85°C.
