APR3001/2/3
MicroPower Microprocessor Reset Circuit
Features
General Description
• 1.2V to 6V Input Voltage Range
• Low Quiescent Current : less than 1.5 µA
• High Accuracy Detection Threshold : ±1.5%
The APR3001/2/3 are designed to monitor voltage sup-
plies in µP 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 are oper-
• Fixed Trimmed Reset Thresholds for 1.5V, 1.75V, ^{ated by monitoring the system power supply voltage.}
2.32V, 2.63V, 2.93V, 3.08V, 3.9V, 4.38V.
• Reset Timeout Period 250ms
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
• 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
series are available with three output stage versions :
APR3001 push-pull active low output, APR3002 push-
pull active high output and APR3003 open drain active low
output. They are also designed to reject fast line transient
glitches on Vcc. The APR3001/2/3 come in a miniature
SOT-23, SOT-23-5, and SOT-89 packages.
