PST853A
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 separated sense pin. The output don't occur to turn over without minimum operating limit voltage by separated sense and power supply pin. Therefore the IC is suitable for low voltage detection applications.
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
Features
High accuracy detection,
Low current consumption
