0 ASM161 / ASM162 µP Supervisory Circuit Key Features monitor power supplies in • • • • • • Edge triggered manual reset input single pulse output 49µS minimum MR disable period after reset CMOS/TTL logic or switch interface Debounced input Low supply current extends battery life • 6µA / 15µA typ/max at 5.
5V • 4.
5µA / 10µA typ/max at 3.
6V Long reset period • 0.
8 sec minimum, 2 sec maximum Two reset polarity options • ASM161: Active LOW, open-drain • ASM162: Active HIGH Pinout matches the AS811/812 Small 4-Pin SOT-143 package Two temperature ranges: 00 to 700c and -400c to +850c General Description The ASM161 and ASM162 are cost effective, low power supervisory circuits that microprocessor, microcontroller and digital systems.
If the power supply drops below the reset threshold level, a reset is asserted and remains asserted for atleast 800ms after VCC has risen above the reset threshold.
An improved manual reset architecture gives the system des...
