Features
General Description
The AP1701/2/3/4 are used for microprocessor (µP) supervisory
circuits to monitor the power supplies in µP and digital systems.
They provide excellent circuit reliability and low cost by
eliminating external components and adjustments when used
with +5V, +3.3V, +3.0V powered circuits.
• Precision Monitoring of +2.5V, +3V, +3.3V, and +5V
Power-Supply Voltages
• Fully Specified Over Temperature
• Available in three Output Configurations
• Push-Pull
RESET Low Output (AP1701/3)
These circuits perform a single function: they assert a reset
signal whenever the V
CC
supply voltage declines below a preset
threshold, keeping it asserted for at least 240ms after V
CC
has
risen above the reset threshold. Reset thresholds suitable for
operation with a variety of supply voltages are available. The
AP1701/2/3/4 have push pull outputs. The AP1701/3 have an
active low
RESET output, while the AP1702/4 has an active
high RESET output. The reset comparator is designed to ignore
fast transients on V
CC
, and the outputs are guaranteed to be in
the correct logic state for V
CC
down to 1V. Low supply current
makes the AP1701/2/3/4 ideal for use in portable equipment. The
AP1701/2/3/4 is available in a 3-pin SC59 package.
• Push-Pull
RESET High Output (AP1702/4)
• 200ms Min. Power-On Reset Pulse Width
• 20µA Supply Current (Typ.)
• Guaranteed Reset Valid to V
