 General DescriptionPaa嘉泰姆

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

supplies in µP and digital systems. The quiescentPaa嘉泰姆

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

ideal for portable battery operated equipment. ThePaa嘉泰姆

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

power supply voltage. When the input voltage dropsPaa嘉泰姆

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

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

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

able with three output stage versions : APR3021Paa嘉泰姆

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

tive high output and APR3023 open drain active lowPaa嘉泰姆
