APR3021/2/3
MicroPower Microprocessor Reset Circuit
Features
General Description
1.2V to 5.5V Input Voltage Range
The APR3021/2/3 are designed to monitor voltage
Low Quiescent Current : less Than 1.5 µA
supplies in µP and digital systems. The quiescent
High accuracy detection threshold : ±1.5%
current is extremely low, typically 1.5 µA, making it
Fixed trimmed reset thresholds for 1.5V, 1.75V, ideal for portable battery operated equipment. The
2.32V, 2.63V, 2.93V, 3.08V, 3.9V, 4.38V.
Reset Timeout Period 250ms
Available output configurations
- Open-drain output
- CMOS active high output
- CMOS active low output
SOT-23 , SOT-23-5 and SOT-89 packages
No external components
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

output. They are also designed to reject fast line tran-
sient glitches on Vcc. The APR3021/2/3 are come in
