ASM6381 - ASM6390
Single/Dual Low Voltage, Low Power Microcontroller Power Supply Supervisor
General Description
The ASM6381 - ASM6390 are cost effective +1.8V to +5V
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.
A reset signal is issued if the power supply voltage drops below
a preset reset threshold and is asserted for a minimum reset
timeout period after the supply has risen above the reset
threshold. The reset timeout periods are available from 1ms to
1200ms. The ASM6381, ASM6384 and ASM6387 have a push-
pull active-low reset output. The ASM6382, ASM6385 and
ASM6388 have a push-pull active-high reset output, and the
ASM6383, ASM6386, ASM6389 and ASM6390 have an open-
drain active-low reset output. The ASM6384, ASM6385 and
ASM6386 also feature a manual reset input.
The ASM6387, ASM6388, ASM6389 have an auxiliary input
RESET IN for monitoring a second voltage. The ASM6390
offers a manual reset input with a longer V
CC
reset timeout
period and a shorter manual reset timeout.
The reset output state is guaranteed to be in the correct logic
state for V
CC
down to 1V. The reset comparator is designed to
ignore fast transients on V
CC
.
• Factory-set Reset Threshold Voltages ranging from +1.58V
to 4.63V.
• Monitor 1.8V to 5V supplies.
• Push-Pull Active-low reset valid with 1.0V supply.
• Small 3-pin SC-70, 4-pin SC-70, 3-pin and 5-pin SOT23
packages.
• No external components.
• Specified over full temperature range: -40°C to 125°C
• Seven Reset Timeout periods: 1ms, 20ms, 140ms, 280ms,
560ms, 1120ms, 1200ms (min).
• Low power consumption: 3µA at +1.8V.
• Auxiliary RESET IN
• Manual Reset input.
Low supply current makes the ASM6381 - ASM6390 ideal for
use in portable and battery operated equipments. The
ASM6381 - ASM6383 are available in a compact, industry
standard 3-pin SC70 package and the ASM6384 - ASM6390
are available in a compact, industry standard 4-pin SC70
package. The ASM63811, ASM63812,
3-pin and 5-pin SOT23 package.
Reset thresholds are available from +1.58V to 4.63V in
approximately 100mV increments to support +1.8V to +5V
systems.
ASM63832 are
available in 3-pin SOT23 package. ASM63813 is available in
