Datasheet BL8506 (Belling)

BL8506 High-Precision Low Voltage Detector DESCRIPTION FEATURES
BL8506 is a series of high precision voltage • High-precision detection voltage: ±2% detector with ultra-low current consumption • Detection voltage: 0.9V~6.0V (in 0.1V step) (500nA typ. at VDD=3.0V). It can work at very low • Precise hysteresis: 4% (Typ.) voltage, which makes it perfect for system reset. • Operating voltage range: 0.7V~10V BL8506 is composed of high precision voltage • Ultra-low current consumption: reference, comparator, output driver and resistor 500nA typ. (at VDD=3.0V) array. Internally preset detect voltage has a low • Two output forms: temperature drift and requires no external CMOS (active low) or trimming. N-channel open-drain (active low)

Two forms of output, CMOS and N-channel open-
APPLICATIONS
drain, are available. • Power monitor for portable equipment such BL8506 is available in SOT23, SOT23-3, SOT23-5, as PDA, DSC, mobile phone, notebook, MP3 SC-82, SOT89-3, TO-92 packages which are Pb-free. • CPU and logic circuit reset • Battery checker • Battery back-up circuit • Power failure detector
