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.
Features：
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
V
DD
＝3.0V)
Two Output forms
：CMOS
and N-channel
open-drain
Application：
Power monitor for portable equipment such as
PDA,DSC,Mobile phone,Notebook,MP3
CPU and Logic Circuit Reset
Battery Checker
Battery Back-up Circuit
