3 Pin Microcontroller Power Supply Supervisor
General Description
The ASM809/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
ASM809/810 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
has an active-low RESET output that is guaranteed to be in the
correct logic state for V
CC
down to 1.1V. The ASM810 has an
active-high RESET output. The reset comparator is designed to
ignore fast transients on V
CC
.
Low supply current makes the ASM809/ASM810 ideal for use
