MicroPower Microprocessor Reset Circuit

General Description

The APR3011/2/3 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
APR3011/2/3 operate by monitoring the system
power supply voltage. When the input voltage drops
below a fixed threshold, the device asserts a reset
signal for a fixed time period after Vcc rises above
the fixed threshold. The APR3011/2/3 series is avail­able with three output stage versions : APR3011
push-pull active low output, APR3012 push-pull ac­tive high output and APR3013 open drain active low
output. They are also designed to reject fast line tran­sient glitches on Vcc. The APR3011/2/3 are come in
a miniature SOT-23, SOT-23-5, SOT-89 packages.
