PT8A2511BPEX

Programmable Timers And Oscillators Overview

The PT8A2511BPEX is a CMOS LSI toaster controller manufactured by Diodes Incorporated. It provides integrated control for toasting, defrosting, and reheating functions within a single chip. The device operates on a supply voltage ranging from 3.5V to 5.5V with a typical current consumption of 100µA at 4.0V. It features an internal oscillator requiring only external components R1 (56kΩ) and C1 (223pF) to set the frequency to 1024Hz. The component is housed in an 8-pin DIP package.

Programmable Timers And Oscillators Feature Summary

• Integrated Defrost and Reheat modes activated via negative pulses on dedicated input pins
• Low power consumption with 100µA typical supply current
• Minimal external component requirements for oscillator and control circuits
• High active relay drive output capable of sourcing up to 15mA

Programmable Timers And Oscillators Applications

• Toaster appliances requiring multiple heating modes
• Small kitchen appliance control systems

Programmable Timers And Oscillators Procurement Notes

Verify that the 'E' suffix confirms lead-free composition and the 'X' suffix indicates tape and reel packaging. Confirm the manufacturer designation as Diodes Incorporated or Pericom Semiconductor Corporation based on the specific production lot. Ensure the DIP-8 package matches the required mechanical footprint for the target PCB design.

Programmable Timers And Oscillators Selection Notes

Select this component for applications requiring a low-cost, single-chip solution for toaster timing and mode selection. Ensure the operating environment stays within the recommended temperature range of 0°C to +85°C. Verify that the system voltage remains between 3.5V and 5.5V to maintain proper logic levels and oscillator stability.

Programmable Timers And Oscillators Part Context

This part belongs to the PT8A2511 family of toaster controllers. The base model PT8A2511PE utilizes an 8-pin DIP package. The 'W' suffix denotes an SOIC-8 package variant. The 'X' suffix specifically adds tape and reel packaging for automated assembly processes.
