General Description
The APR3021, APR30212,APR30213 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
APR3021/2/3 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 APR3021/2/3 series is avail-
able with three output stage versions : APR3021
push-pull active low output, APR3022 push-pull ac-
tive high output and APR3023 open drain active low
Applications
output. They are also designed to reject fast line tran-
sient glitches on Vcc. The APR3021/2/3 are come in
