BL8506D
High-precision Low Voltage Detector
Features：
：
Outline:
•
BL8506D is a series of high precision
voltage detector with ultra low current
consumption (250nA typ. at VDD=VTH+1V ). It
can work at very low voltage, which makes it
perfect for system reset.
BL8506D 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.
BL8506D is available in SOT-89-3,SOT-233 TO92, SOT23-5 packages which is Pb free.

Function description:
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 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))
