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 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.
Features
High-precision detection Voltage 2%
Detection Voltage 0.9V~6.0V (in 0.1V steps)
Built-in Power on Reset Delay Time
circuit::Refer to Selection Guide
Operating Voltage range 0.7V~10V
Ultra-low current consumption 500nA typ. (at
VDD 3.0V)
Two Output forms CMOS and N-channel
open-drain (Active Low)
Two type of output, CMOS and N-channel
open-drain are available.
BL8509 is available in SOT-23 which is Pb
free.
