High-Precision Low Voltage Detector

BL8506

DESCRIPTION

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 are 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 VDD＝3.0V)\

 Two Output Forms ：CMOS(Active Low)

and N-channel open-drain(Active Low)

APPLICATIONS

 Power monitor for portable equipment

such as PDA,DSC,Mobile

phone,Notebook,MP3

 CPU and Logic Circuit Reset

 Battery Checker

 Battery Back-up Circuit

 Power Failure Detector

TYPICAL APPLICATION

Note：

 R0 is unnecessary for CMOS output

products.,

 The value of R0 need to be selected in

different application, Typical value is 470k

Ω
