PT8A2512NE

Programmable Timers And Oscillators Overview

The PT8A2512NE is a CMOS LSI chip designed for simple toaster applications, providing a low-cost control solution. It operates within a supply voltage range of 3.5V to 5.5V and features an integrated system oscillator and frequency divider. The device provides a one-stop timer function that automatically shuts down the relay output after approximately 30 seconds upon power-on. It utilizes a TO-94 package with four pins: RELAY (output), VCC (power), OSC (oscillator I/O), and GND.
