3-Pin Microcontroller Power Supply Supervisor  
Six voltage thresholds are available to support 3V to 5V  
systems:  
General Description  
The ASM809/ASM8091/ASM810 are cost effective 3.0V, 3.3V  
and 5.0V power supply supervisor circuits optimized for low-  
power microprocessor (µP), microcontroller (µC) and digital  
systems. They provide a reset output during power-up, power-  
down and brown-out conditions. They provide excellent  
reliability by eliminating external components and adjustments.  
The ASM809/ASM8091/ASM810 are improved drop-in  
replacements for the Maxim MAX809/810 and feature 60%  
lower supply current.

A reset signal is issued if the power supply voltage drops below  
a preset reset threshold and is asserted for at least 140mS after  
the supply has risen above the reset threshold. The ASM809/  
ASM8091 has an active-low RESET output that is guaranteed  
to be in the correct logic state for VCC down to 1.1V. The

ASM810 has an active-high RESET output. The reset  
comparator is designed to ignore fast transients on VCC
