TSC2046EIPW Datasheet PDF - TI

●The TSC2046EIPW is a 4-wire Touch Screen Controller with low voltage digital I/O and extended ESD protection. The TSC2046E is 100% pin-compatible with the existing ADS7846 and drops into the same socket. This design allows for an easy upgrade of current applications to the new version. It 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 a supply voltage of 2.7V, while monitoring the battery voltage from 0 to 6V. The low-power consumption of <0.75mW typ at 2.7V (reference off), high-speed (up to 125kHz sample rate) and on-chip drivers make the TSC2046E an ideal choice for battery-operated systems such as personal digital assistants (PDAs) with resistive touch screens, pagers, cellular phones and other portable equipment.
