TSC2046IGQCR-90

The TSC2046IGQCR-90 is designed as a next-generation version to the ADS7846 4-wire touch screen controller which supports a low-voltage I/O interface from 1.5V to 5.25V. It is 100% pin compatible with the existing ADS7846, and will drop into the same socket. This allows for easy upgrade of current applications to the new version.

TSC2046IGQCR-90 has ten features. (1)Same pinout as ADS7846. (2)2.2V to 5.25V operation. (3)1.5V to 5.25V digital I/O. (4)Internal 2.5V reference. (5)Direct battery measurement (0V to 6V). (6)On-chip temperature measurement. (7)TOUCH-pressure measurement. (8)QSPI and SPI 3-wire interface. (9)Auto power-down. (10)Available in TSSOP-16, QFN-16 and VFBGA-48 packages. Those are all the main features.

Some TSC2046IGQCR-90 absolute maximum ratings have been concluded into several points as follow. (1)Its +Vcc and IOVDD to GND would be from -0.3V to +6V. (2)Its analog inputs to GND would be from -0.3V to Vcc+0.3V. (3)Its digital inputs to GND would be from -0.3V to IOVDD+0.3V. (4)Its power dissipation would be 250mW. (5)Its maximum junction temperature would be 150°C. (6)Its operating temperature range would be from -40°C to 85°C. (7)Its storage temperature range would be from -65°C to 150°C. (8)Its lead temperature soldering 10 seconds would be 300°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some TSC2046IGQCR-90 electrical characteristics are concluded as follow. (1)Its analog input full-scale input span would be min 0V and max Vref. (2)Its absolute input range would be min -0.2V and max Vcc+0.2V for positive input and would be min -0.2V and max +0.2V for negative input. (3)Its capacitance would be typ 25pF. (4)Its leakage current would be typ 0.1uA. (5)Its system performance resolution would be typ 12bits. And so on.
