APR3011/2/3
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 APR3011/2/3 are designed to monitor voltage sup-
plies in µP and digital systems. The quiescent current is
extremely low, typically 1.5µA, making it ideal for portable
battery operated equipment. The APR3011/2/3 operate
• Fixed Trimmed Reset Thresholds for 1.5V, 1.75V, ^{by monitoring the system power supply voltage. When}
2.32V, 2.63V, 2.93V, 3.08V, 3.9V, 4.38V, 4.63V
• Reset Timeout Period 250ms
the input voltage drops below a fixed threshold, the de-
vice asserts a reset signal for a fixed time period after Vcc
rises above the fixed threshold. The APR3011/2/3 series
• Available Output Configurations
- Open-Drain Output
- CMOS Active High Output
- CMOS Active Low Output
• SOT-23-3, SOT-23-5, and SOT-89 Packages
are available with three output stage versions: APR3011
push-pull active low output, APR3012 push-pull active
high output, and APR3013 open drain active low output.
They are also designed to reject fast line transient glitches
on V_CC. The APR3011/2/3 come in a miniature SOT-23-3,
SOT-23-5, and SOT-89 packages.
