TSC2007IPWRQ1

Overview

The TSC2007IPWRQ1 is a 12-bit, nanopower resistive touch-screen controller designed for automotive applications. It operates on a single supply voltage ranging from 1.2 V to 3.6 V and features an I²C interface for communication with host processors. The device integrates a temperature sensor, a 12-bit analog-to-digital converter (ADC), and a programmable serial interface. Key functional blocks include a battery monitor, a reference buffer, and a low-dropout regulator. It supports four-wire resistive touch panels and includes internal filtering capabilities to reduce noise during sampling.

Feature Summary

• 12-bit resolution ADC with up to 125 kS/s sampling rate
• I²C serial interface compatible with standard and fast-mode protocols
• Integrated temperature sensor and battery monitor
• Automotive qualification compliant with AEC-Q100 standards

Applications

• Automotive infotainment systems
• In-cluster instrument displays
• Rear-seat entertainment screens

Procurement Notes

Verify the suffix IPWRQ1 indicates the automotive grade and TSSOP-16 package configuration. Confirm RoHS compliance and lead times through authorized distributors. Ensure the ordering part number matches the specific temperature range and packaging requirements for the target assembly process.

Selection Notes

Select this component when an I²C interface is required instead of SPI. It is suitable for designs needing integrated temperature sensing or battery monitoring alongside touch control. Compare power consumption against the TSC2008 if SPI connectivity is mandatory. Verify that the 1.2 V minimum supply voltage aligns with the system's power rail availability.

Part Context

This part belongs to the TSC200x family of nanopower touch-screen controllers from Texas Instruments. The 'Q1' suffix denotes automotive qualification under AEC-Q100 standards. It serves as a specialized data converter within human-machine interface subsystems, bridging analog touch inputs to digital processing units.

Replacement Considerations

The TSC2007IPW is the commercial-grade equivalent without automotive qualification. For SPI-based interfaces, consider the TSC2006 or TSC2008 series. Cross-model substitution requires verifying interface compatibility and pin assignments.
