PST894R
Overview
This IC is a System Reset IC that detect
turn-off or the power flicker in power supply of CPU or logic systems.
The IC has the delay time pin by an external capacitor and manual reset sense pin. The manual reset function can reset for system at any time.
Therefore the IC is suitable for some applications of forced reset or test function.
Application
・Reset circuits for microcomputers, CPUs and MPUs
・Reset circuits for logic circuits
・Battery voltage check circuits
・Back-up power supply switching circuits
・Level detection circuits
