APR3002

APR3001/2/3 MicroPower Microprocessor Reset Circuit 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. Reset Timeout Period 250ms Available output configurations - Open-drain output - CMOS active high output - CMOS active low output General Description The APR3001/2/3 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 APR3001/2/3 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 APR3001/2/3 series is 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 are come in a miniature SOT-23, SOT-23-5, SOT-89 packages.
