BL8504

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 TYPICAL APPLICATION BL8504 ELECTRICAL CHARACTERISTICS Supply current(A) Detector threshold= 0.9V 1.
