Industry-standard reset IC <809 series>
Increased accuracy, Low current consumption,
No external capacitor required high CP product
Reset IC with Built-In Delay Circuit
PST809 series
Announced on September 27, 2011
Overview
The product (SOT-23A) was developed to be compatible with the standard IC "809 series" of built-in delay resets. The <PST809 series> does not require an external capacitor because it is equipped with a built-in delay circuit, and its small package requires less mounting space.
The detection voltage accuracy (±1.5%), low consumption current (0.5μA typ.) and advanced specifications support personal computer demands for low voltage, increased detection voltage accuracy, and low current consumption.
