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. • • SOT-23 , SOT-23-5 and SOT-89 packages No external components Applications • • • • Computers Cell Phones Portable Electronics µP Power Supply Monitoring Pin Configuration V CC 3 1 2 NC NC 5 1 2 4 3 (3 0 0 1 /3 ) R e s e t G N D (3 0 0 2 ) R e s e t (3001/3) Reset V CC GND (3002) Reset SOT-23 (Top View) SOT-23-5 (Top View) 1 2 3 (3001/3) Reset (3002) Reset V CC GND SOT-89 (Top View) ANPEC reserves the right to make changes to improve reliability or manufacturability without notice, and advise customers to obtain the latest version of relevant information to verify before placing orders.
