TSC2017IYZGT

Overview

The TSC2017IYZGT is a resistive touch screen controller manufactured by Texas Instruments. It features a 12-bit resolution and supports sampling rates up to 154 kS/s. The device operates on a supply voltage range of 1.65 V to 3.6 V with an operating supply current of 285 uA. It accommodates temperatures from -40°C to +85°C and utilizes a DSBGA-12 surface-mount package.

Feature Summary

• 12-bit resolution for precise coordinate detection
• Sampling rate up to 154 kS/s
• Low power consumption at 285 uA
• DSBGA-12 compact package

Applications

• Resistive touch screen interface in portable devices
• Embedded systems requiring low-power touch input
• Industrial control panels with resistive overlays

Procurement Notes

Verify the specific suffix 'IYZGT' against the official datasheet to confirm temperature grade, package type, and tape/reel specifications. Ensure compatibility with system voltage levels between 1.65 V and 3.6 V before procurement.

Selection Notes

Select this component when a 12-bit resolution and 154 kS/s sampling rate are required for resistive touch applications. Consider the DSBGA-12 package size constraints and the -40°C to +85°C operating temperature range relative to the target environment.

Part Context

This part belongs to the TSC2017 series of touch screen controllers from Texas Instruments. It is designed specifically for interfacing with 4-wire resistive touch screens, providing analog-to-digital conversion for X, Y, and Z coordinates.

Replacement Considerations

Check for direct pin-compatible substitutes within the TSC2000 or TSC2007 series if available, ensuring identical interface protocols and electrical characteristics match the design requirements.
