General Description
AAT3520 General Description
The AAT3520 Series of PowerManager™ products is a member of AnalogicTech™'s Total Power Management™ IC (TPM ICs™) product family. These microprocessor reset circuits are ideal for monitoring voltage supplies in portable systems, where extended battery life is critical. They provide a low cost, reliable solution by eliminating external components. The AAT3520 series operates 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 has risen back above the fixed threshold; 30ms and 150ms minimum periods are available. The AAT3520 product series is guaranteed to operate down to 1.2V and designed to ignore fast line transients appearing on VCC. The AAT3520 series is available with three output stage versions: AAT3520 push-pull active high output, AAT3522 push-pull active low output and AAT3524 open drain active low output. The quiescent supply current is extremely low, typically 1A, making it ideal for portable battery operated equipment.
The AAT3520/2/4 are available in a 3 pin SOT23 package and are specified over -40° to 85°C operating temperature range.
