| BL8506 High-precision Low Voltage Detector Outline: BL8506 is a series of high precision voltage detector with ultra low current consumption (500nA typ. at Vdd=3.0V). It can work at very low voltage, which makes it perfect for system reset. BL8506 is composed of high precision voltage reference, comparator, 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. BL8506 is available in SOT-89-3,SOT-23-3 TO92, SOT23-5 packages which is Pb free.

Input voltage, divided by resistor array of Ra Rb and Rc, is applied to the positive input of the comparator. Output of the comparator controls a pair of NMOS and PMOS switches, generating the hysteresis. Output of the comparator passes a series of buffer to drive the output CMOS pair. + VDET - VDET VHYS can be calculated as follows: - VDET =VREF*(1+Ra/(Rb+Rc)) + VDET =VREF*(1+(Ra+Rd)/Rb)= VREF *(1+(Ra+Rc)/Rb) VHYS=+ VDET -(- VDET)= VREF*(Ra+Rb+Rc)(1/Rb-1/(Rb+Rc)) www.belling.com.cn Ver1.1 8 BL8506 No. I II III IV V Operation status VDD>-VDET VDD drops below - VDET VDD drops further below VDDL VDD rises above VDDL VDD rises above + VDET Output status Output voltage is equal to the supply voltage Output voltage equals to GND level Output voltage is undefined Output voltage equals to GND level Output voltage equals to supply voltage VHYS=(+ VDET)-(- VDET) www.belling.com.cn Ver1.1 9 BL8506 Test circuits 1(c) Supply current test circuit 2(c) Detector threshold test circuit 3(c) NCH Drive Output Current Test Circuit 4(c) PCH Drive Output Current Test Circuit www.belling.com.cn Ver1.1 10 BL8506 Typical Performance Characteristics 1) Output voltage VS.
