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 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.
BL8509 is available in SOT-23 which is Pb
free. |
