Ultra Low Power Microprocessor Reset IC

CN803/809/CN810

General Description

Features

The CN803/809/810 series are micro- processor

(µP) supervisory circuits used to monitor the

power supplies in µP and digital systems. They

provide excellent circuit reliability and low cost

by eliminating external components.



Precise Reset Threshold: ±2.5%

CMOS Output(CN809/810) and Open Drain

Output(CN803)



140ms min Reset Pulse Width

3.2µA Supply Current @V_CC=3V

Guaranteed Reset Valid to V_CC= +1.15V

Power Supply Transient Immunity

Operating Temperature Range

-40°C to +85°C

These circuits perform a single function: they

assert a reset signal whenever the V_CCsupply

voltage declines below a preset threshold, keeping

it asserted for at least 140ms after V_CChas risen

above the reset threshold.



Available in SOT23-3

The CN809/810 have CMOS outputs, the CN803

has open drain output. The CN803/809 have an

active-low

output, while the CN810 has

an active-high RESET output. The reset

correct logic state for V_CCdown to 1.15V over the

temperature range.
