PT8A2516TAE

Programmable Timers And Oscillators Overview

The PT8A2516TAE is a CMOS LSI simple timer manufactured by Diodes Incorporated in a lead-free and green SOT-23-5L package. It operates within a supply voltage range of 3.5V to 5.5V and features an adjustable timer duration from 20 minutes to 16 hours, determined by external R/C components. The device includes a built-in power-on reset circuit, logic control, output driver, key scan circuit, and internal oscillator. It provides a high-active relay output capable of sourcing up to 10mA or sinking up to 100µA. An external R/C oscillator can be configured for approximately 8.192kHz using a 47kΩ resistor and 332 capacitor.

Programmable Timers And Oscillators Feature Summary

• Adjustable timer ranging from 20 minutes to 16 hours via external R/C network
• Integrated power-on reset circuit and internal oscillator for system stability
• Supports Quick Test Mode (QTM) for manufacturing efficiency
• High-active Relay output pin with integrated drive capability

Programmable Timers And Oscillators Applications

• Timer circuits requiring fixed or adjustable time delays

Programmable Timers And Oscillators Procurement Notes

Verify the specific ordering suffix 'TA' corresponds to the SOT-23-5L package configuration as documented. Confirm that the 'E' suffix indicates Pb-free and Green material compliance. Ensure the application design accommodates the specified operating temperature range of -40°C to 85°C and the maximum storage temperature of 125°C.

Programmable Timers And Oscillators Selection Notes

Select this component when a low-cost, single-channel timer with direct relay drive is required. The timing interval is flexible based on external R/C values, allowing customization between 20 minutes and 16 hours. Consider the SOT-23-5L package for space-constrained surface-mount designs. Ensure the load connected to the Relay pin does not exceed the DC output current limits of 10mA source or 100µA sink.

Programmable Timers And Oscillators Part Context

The PT8A2516 belongs to the PT8A25xx series of universal timer controllers designed for AC/DC power applications. It shares functional similarities with other models in the series but offers specific timing ranges and package options. The TAE variant specifically denotes the SOT-23-5L package with lead-free and green specifications, distinguishing it from through-hole alternatives like the TO94-4L version.

Programmable Timers And Oscillators Replacement Considerations

Direct replacements must match the SOT-23-5L footprint and support the 3.5V–5.5V operating voltage. Verify that substitute devices offer comparable adjustable timer ranges and relay drive capabilities. Check for compatibility with the external R/C oscillator requirements if precise timing accuracy is critical.
