TacTouch, Low-Power, Ultra-Small, Resistive
Touch-Screen Controller with Haptic Driver MAX11811
General Description
The MAX11811 low-power touch-screen controller oper-
ates from a 1.7V to 3.6V single supply targeting power-
sensitive applications such as handheld equipment. The
device contains a 12-bit SAR ADC and a multiplexer to
interface with a resistive touch-screen panel. A digital
serial interface provides communications.
The MAX11811 includes digital preprocessing of the
touch-screen measurements, reducing bus loading
and application processor (AP) resource requirements.
The included smart interrupt function generator greatly
reduces the frequency of interrupt servicing to the devic-
es. The MAX11811 enters low-power mode automatically
between conversions to save power, making the device
ideal for portable applications.
The MAX11811 offers two modes of operation: direct
and autonomous. Direct mode allows the application
processor to control all touch-screen controller activ-
ity. Autonomous mode allows the MAX11811 to control
touch-screen activity, thereby freeing the application
processor to perform other functions. In autonomous
mode, the device periodically scans the touch screen
for a touch event without requiring host processor
intervention. This can be used to reduce system power
consumption. An on-chip FIFO is used during autono-
mous mode to store results and increase effective data
throughput and lower system power.
The MAX11811 supports data-tagging, which records
the type of measurement performed; X, Y, Z1, or Z2, and
the type of touch event; initial touch, continuing touch, or
touch release.
The MAX11811 features a haptic driver to either drive a
vibration motor directly or to interface with an external
piezo actuator driver. The device generates PWM sig-
nals that can drive the MAX11835 haptic piezo control-
ler. The device includes a general-purpose current DAC
output and a general-purpose input that can be used to
drive IR and visible LEDs, as well as IR photo-detectors
in applications such as proximity detectors.
The MAX11811 supports the I2C serial bus. The
MAX11811ETP+ is available in a 20-pin TQFN package
and is specified over the extended industrial tempera-
ture range of -40NC to +85NC. The MAX11811GTP/V+ is
specified over the -40NC to +105NC automotive tempera-
ture range.
