TSC2046触摸屏控制IC资料

The TSC2046 is 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. The TSC2046 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. The TSC2046 also has an on-chip 2.5V reference that can be used for the auxiliary input, battery monitor, and temperature measurement modes. The reference can also be powered down when not used to conserve power. The internal reference operates down to 2.7V supply voltage, while monitoring the battery voltage from 0V to 6V.
