BL8506D
High-precision Low Voltage Detector
Outline:
BL8506D is a series of high precision
voltage detector with ultra low current
consumption (250nA typ. at
VDD=V
TH
+1V
). It
can work at very low voltage, which makes it
perfect for system reset.
BL8506D 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.
Two type of output, CMOS and N-channel
open-drain are available.
BL8506D is available in SOT-89-3,SOT-23-
3 TO92, SOT23-5 packages which is Pb free.
