DESCRIPTIONThe TSC2046 is a next-generation version to the
ADS7846 4-wire touch screen controller which supports 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.
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 TSC2046 an ideal choice for
battery-operated systems such as personal digital
assistants (PDAs) with resistive touch screens, pagers,
cellular phones, and other portable equipment. The
TSC2046 is available in TSSOP-16, QFN-16, and
VFBGA-48 packages and is specified over the –40°C to
+85°C temperature range.
