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.
