APR3011/2/3
MicroPower Microprocessor Reset Circuit
Features
General Description
• 1.2V to 6V Input Voltage Range
The APR3011/2/3 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
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 avail-
able with three output stage versions : APR3011
push-pull active low output, APR3012 push-pull ac-
tive high output and APR3013 open drain active low
Applications
output. They are also designed to reject fast line tran-
sient glitches on Vcc. The APR3011/2/3 are come in
• Computers
• Cell Phones
• Portable Electronics
• µP Power Supply Monitoring
a miniature SOT-23, SOT-23-5, SOT-89 packages.
