BL8509Low Voltage Detector with Built-in Delay CircuitOutline: BL8509 is a series of high precision voltage detector with ultra low current consumption (500nA typ. at Vdd=3.0V) and a built-in delay circuit. It can work at very low voltage, which makes it perfect for system reset. BL8509 is composed of high precision voltage reference, comparator, delay circuit, output driver and resistor array. Internally preset detect voltage has a low temperature drift and requires no external trimming. Two type of output, CMOS and N-channel open-drain are available. BL8509 is available in SOT-23 which is Pb free.FeaturesHigh-precision detection VoltageDetection VoltageBuilt-in Power on Reset Delay Time circuit::Refer to Selection GuideOperating Voltage range0.7V~10V500nA typ.

BL8509Function description: Delay Comparator High precision low temperature co-efficiency reference voltage is applied to the negative input of a comparator. Input voltage, divided by resistor array of Ra and Rb, is applied to the positive input of the comparator. Output of the comparator passes a delay circuit and a series of buffer to drive the output CMOS pair. VDET =VREF*(1+Ra/Rb) http://www.belling.com.cn- 8- Total17 Pages8/8/2006元器件交易网www.cecb2b.com
