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 9 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 www.belling.com.cn 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) 10 BL8506 TEST CIRCUITS （1）Supply current test circuit （2）Detector threshold test circuit BL8506 BL8506 （3）NCH Drive Output Current Test Circuit （4）PCH Drive Output Current Test Circuit BL8506 BL8506 www.belling.com.cn 11 BL8506 TYPICAL PERFORMANCE CHARACTERISTICS 1) Output voltage VS.
