APR3101

APR3101/2/3 MicroPower Microprocessor Reset Circuit with Manual Reset Features 1.2V to 6V Input Voltage Range Low Quiescent Current : less Than 1.5 µA High accuracy detection threshold : ±1.5% Fixed trimmed reset thresholds for 1.5V, 1.75V, 2.32V, 2.63V, 2.93V, 3.08V, 3.9V, 4.38V. Manual Reset Input Reset Timeout Period 250ms Available output configurations - Open-drain output - CMOS active high output - CMOS active low output SOT-23-5 package No external components General Description The APR3101/2/3 are designed to monitor voltage supplies in µP and digital systems. The quiescent current is extremely low, typically 1.5 µA, making it ideal for portable battery operated equipment. The APR3101/2/3 operate by monitoring the system power supply voltage. When the input voltage drops below a fixed threshold or whenever manual reset is asserted, the device asserts a reset signal for a fixed time period after Vcc rises above the fixed threshold or manual reset is deasserted. The APR3101/2/3 series is available with three output stage versions:APR3101 pushpull active low output, APR3102 push-pull active high output and APR3103 open drain active low output. The APR3101/2/3 also have a debounced manual reset Applications Computers Cell Phones Portable Electronics µP Power Supply Monitoring input that is provided to override the reset monitor. They are also designed to reject fast line transient glitches on Vcc. The APR3101/2/3 are come in a miniature SOT-2...
