 General Descriptionh27嘉泰姆

The APR3021, APR30212,APR30213 are designed to monitor voltageh27嘉泰姆

supplies in µP and digital systems. The quiescenth27嘉泰姆

current is extremely low, typically 1.5 µA, making ith27嘉泰姆

ideal for portable battery operated equipment. Theh27嘉泰姆

APR3021/2/3 operate by monitoring the systemh27嘉泰姆

power supply voltage. When the input voltage dropsh27嘉泰姆

below a fixed threshold, the device asserts a reseth27嘉泰姆

signal for a fixed time period after Vcc rises aboveh27嘉泰姆

the fixed threshold. The APR3021/2/3 series is avail-h27嘉泰姆

able with three output stage versions : APR3021h27嘉泰姆

push-pull active low output, APR3022 push-pull ac-h27嘉泰姆

tive high output and APR3023 open drain active lowh27嘉泰姆
