General Description
The APR3101,APR3102,APR3103 are designed to monitor voltage
supplies in µP and digital systems. The quiescent
current is extremely low, typically 1.5 µA, making it
ideal for portable battery operated equipment. The
APR3101/2/3 operate by monitoring the system power
supply voltage. When the input voltage drops below a
fixed threshold or whenever manual reset is asserted,
the device asserts a reset signal for a fixed time pe-
riod after Vcc rises above the fixed threshold or manual
reset is deasserted. The APR3101/2/3 series is avail-
able with three output stage versions:APR3101 push-
pull active low output, APR3102 push-pull active high
output and APR3103 open drain active low output. The
APR3101/2/3 also have a debounced manual reset
Applications
input that is provided to override the reset monitor.
They are also designed to reject fast line transient
