BL8506
High-Precision Low Voltage Detector
DESCRIPTION
FEATURES
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.


High-precision detection Voltage： 2%
Detection Voltage：0.9V~6.0V (in 0.1V
steps)
Precise hysteresis：4% typ.
Operating Voltage range：0.7V~10V
Ultra-low current consumption：500nA
typ. (at VDD＝3.0V)\
Two Output Forms ：CMOS(Active Low)
and N-channel open-drain(Active Low)



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.

APPLICATIONS
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 are Pb free.
Power monitor for portable equipment
such as PDA,DSC,Mobile
phone,Notebook,MP3

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))
