3-Pin Microcontroller Power Supply Supervisor
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 (P), microcontroller (C) 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.
Low supply current makes the ASM809/ASM8091/ASM810
ideal for use in portable and battery operated equipment. The
ASM809/ASM8091/ASM810 are available in a compact,
industry standard 3&5-pin SOT-23 Packages.
Six voltage thresholds are available to support 3V to 5V
systems:
Features:
Monitor 5V, 3.3V and 3V supplies
140mS minimum reset pulse width
Active-low reset valid with 1.1V supply (ASM809/
ASM8091)
Small 3&5-pin SOT-23 Packages
No external components
