General Description
The AMS811 / 812 are low-power microprocessor
(µP) supervisory circuits used to monitor power sup-
plies in µP and digital systems. They provide excellent
circuit reliability and low cost by eliminating external
components and adjustments when used with 5V-
powered or 3V-powered circuits. The AMS811 / 812
also provide a debounced manual reset input.
These devices perform a single function: They assert a
reset signal whenever the VCC supply voltage falls
below a preset threshold, keeping it asserted for at
least 140ms after VCC has risen above the reset thresh-
old. The only difference between the two devices is that
the AMS811 has an active-low RESET output (which is
guaranteed to be in the correct state for VCC down to
1V), while the AMS812 has an active-high RESET out-
put. The reset comparator is designed to ignore fast
transients on VCC. Reset thresholds are available for
operation with a variety of supply voltages.
Low supply current makes the AMS811 / 812 ideal
for use in portable equipment. The devices come in a
4-pin SOT143 package.

_______________Ordering Information
*
This part offers a choice of five different reset threshold volt-
ages. Select the letter corresponding to the desired nominal
reset threshold voltage, and insert it into the blank to complete
the part number.
Devices are available in both leaded and lead-free packaging.
Specify lead-free by replacing “-T” with “+T” when ordering.
