TRAC-S2Q16

Overview

The TRAC-S2Q16 is a support circuit for the TRAC family of Field Programmable Analog Devices, manufactured by Diodes Incorporated. It operates on a split 5V supply with an operating range of 4.8V to 5.2V and standby current of 1.5mA to 1.9mA. The device integrates a rail splitter, supply monitor, and programming logic to simplify interface with memory devices. Key electrical parameters include a RESET_OUT threshold of 4.35V to 4.75V, CLK_OUT frequency of 7kHz to 15kHz (with external capacitor), and AGND_OUT output voltage stability within +/- 0.010V under load. It functions in an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrates rail splitter, supply monitor, and programming logic to reduce component count
• Automatically senses completion of program loading via CLCR_IN input
• Generates user-defined analog ground (AGND_OUT) with +/- 20mA drive capability
• Includes thermal shutdown protection against overheating

Applications

• Supporting TRAC devices during power-up program loading
• Reloading programs after power failure or serious fluctuation
• Simplifying connection between serial output EEPROMs and TRAC devices

Procurement Notes

Verify the specific package variant QSOP-16 and ensure compatibility with existing TRAC device families. Confirm that the design utilizes a split 5V supply architecture as required by the device's operational specifications. Check for updated documentation regarding compatible memory devices such as ST9346CB1 or 93LC46B.

Selection Notes

Select this component when designing systems using TRAC programmable analog devices that require automated initialization and power monitoring. Ensure the application provides a stable 5V supply and allows for external capacitors to set clock frequencies. Verify that the industrial temperature range (-40°C to +85°C) meets environmental requirements.

Part Context

The TRAC-S2Q16 belongs to the TRAC family of support circuits designed to facilitate the rapid implementation of signal processing solutions. It serves as a bridge between custom silicon needs and prototyping, enabling designers to load configuration data into TRAC devices automatically without manual intervention.

Replacement Considerations

No direct public substitute part numbers are documented. This component is specifically engineered for the TRAC ecosystem; alternative support circuits must be evaluated for pin compatibility and functional equivalence with TRAC devices.
