 General DescriptionBmS嘉泰姆

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

supplies in µP and digital systems. The quiescentBmS嘉泰姆

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

ideal for portable battery operated equipment. TheBmS嘉泰姆

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

power supply voltage. When the input voltage dropsBmS嘉泰姆

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

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

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

able with three output stage versions : APR3021BmS嘉泰姆

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

tive high output and APR3023 open drain active lowBmS嘉泰姆
