High-Precision Low Voltage Detector

BL8504

DESCRIPTION

BL8504 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.

BL8504

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.

One type of output, N-channel open-drain is

available.

BL8504 is available in small size SOT23-3

package which is Pb free.

FEATURES

• High-precision detection Voltage： ±3%

• 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)

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
