BL8509D
Low Voltage Detector with Built-in Delay Circuit
Outline:
BL8509D is a series of high precision
voltage detector with ultra low current
consumption (500nA typ. at VDD=VTH+1V) and a
built-in delay circuit. It can work at very low
voltage, which makes it perfect for system reset.
BL8509D is composed of high precision
voltage reference, comparator, 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.
BL8509D is available in SOT-23,SOT-23-
3,SOT-23-5 which is Pb free.
