 General DescriptionUUC嘉泰姆

The APR3021, APR30212,APR30213 are designed to monitor voltageUUC嘉泰姆

supplies in µP and digital systems. The quiescentUUC嘉泰姆

current is extremely low, typically 1.5 µA, making itUUC嘉泰姆

ideal for portable battery operated equipment. TheUUC嘉泰姆

APR3021/2/3 operate by monitoring the systemUUC嘉泰姆

power supply voltage. When the input voltage dropsUUC嘉泰姆

below a fixed threshold, the device asserts a resetUUC嘉泰姆

signal for a fixed time period after Vcc rises aboveUUC嘉泰姆

the fixed threshold. The APR3021/2/3 series is avail-UUC嘉泰姆

able with three output stage versions : APR3021UUC嘉泰姆

push-pull active low output, APR3022 push-pull ac-UUC嘉泰姆

tive high output and APR3023 open drain active lowUUC嘉泰姆
