BL8509 Datasheet Low Voltage Detector

Manufacturer: SHANGHAI BELLING

Overview: .. BL8509 Low Voltage Detector with Built-in Delay Circuit Outline: BL8509 is a series of high precision voltage detector with ultra low current consumption (500nA typ. at Vdd=3.0V) and a built-in delay circuit. It can work at very low voltage, which makes it perfect for system reset. BL8509 is posed of high precision voltage reference, parator, delay circuit, 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. BL8509 is available in SOT-23 which is Pb free.
