μ
P Power Supply Monitoring
The APR3001/2/3 are designed to monitor voltage
supplies in
μ
P and digital systems. The quiescent
current is extremely low, typically 1.5 μA, making it
ideal for portable battery operated equipment. The
APR3001/2/3 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 APR3001/2/3 series is avail-
able with three output stage versions : APR3001
push-pull active low output, APR3002 push-pull ac-
tive high output and APR3003 open drain active low
output. They are also designed to reject fast line tran-
sient glitches on Vcc. The APR3001/2/3 are come in
a miniature SOT-23, SOT-23-5, SOT-89 packages.
