IMP811JEUS-T 技术参数

IMP811, IMP812

Detailed Description

Reset Timing and Manual Reset (MR)

The reset signal is asserted–LOW for the IMP811 and HIGH for

the IMP812 – when the V_CCsignal falls below the threshold trip

voltage and remains asserted for 140ms minimum after the V_CC

has risen above the threshold.

MR may be connected to a normally-open switch connected to

ground without an external debounce circuit.

For added noise rejection, a 0.1µF capacitor from MR to Ground

can be added.

A logic low on MR asserts RESET LOW on the IMP811 and HIGH

on the IMP812. MR is internally pulled high through a 20kΩ

resistor and can be driven by TTL/CMOS gates or with open

collector/drain outputs. MR can be left open if not used.
