PT8A2511WE

Programmable Timers And Oscillators Overview

The PT8A2511 is a dedicated toaster controller IC designed for managing heating cycles and user interface inputs. It operates within a supply voltage range of 3.5V to 5.5V, with a typical operating voltage of 4.0V. The device features an internal oscillator requiring external components R1 (56kΩ) and C1 (223) to set a frequency of 1024Hz. Key electrical characteristics include a maximum power dissipation of 500mW and a junction temperature limit of 125°C. The IC provides specific outputs for relay drive and status indicators, along with inputs for defrost and reheat functions.

Programmable Timers And Oscillators Procurement Notes

The PT8A2511 is marked as PART OBSOLETE - DISCONTINUED in the official datasheet. Verification of current availability requires checking authorized distributors or Diodes Incorporated directly, as standard inventory channels may no longer support this component. Engineering teams should consider alternative solutions due to its discontinued status.

Programmable Timers And Oscillators Selection Notes

This component is suitable for applications requiring a dedicated single-chip solution for basic toaster cycling. Designers must ensure the supply voltage remains between 3.5V and 5.5V. The external oscillator components R1 and C1 must be selected to maintain the 1024Hz frequency within the specified tolerance (952-1096 Hz). The package is available in an 8-pin DIP format.

Programmable Timers And Oscillators Part Context

The PT8A2511 belongs to Diodes Incorporated's line of specialized application-specific integrated circuits for consumer appliances. It is packaged in an 8-DIP (P) configuration. The part number suffix 'PE' indicates a Pb-free and Green compliant version, while 'X' denotes tape and reel packaging.

Programmable Timers And Oscillators Replacement Considerations

As the PT8A2511 is officially discontinued, direct replacement requires evaluating functional equivalents from other manufacturers or newer generations of Diodes products. No specific substitute part numbers are listed in the provided documentation; system redesign may be necessary to accommodate different pinouts or control logic.
