BL8504
High-Precision Low Voltage Detector
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
