MAX11811 Touch Evaluation System (TEVS)

General Description

The MAX11811 touch evaluation system (TEVS)

demonstrates the rich features of the MAX11811 touch-

screen controller (TSC) and allows its evaluation. The TEVS

consists of a USB interface board (UTIBB+), MAX11811

evaluation kit (EV kit), and a 4-wire touch sensor

mounted with an linear resonant actuator (LRA) motor

(USB cable included).

The device is a complete resistive touch-sensor

controller solution that targets touch-enabled

devices with small- to medium-size displays. The device

enables miniaturization of consumer products due to its

ultra-small size. Its low power consumption makes it

attractive for portable devices.

The TEVS with haptics operates directly from the USB

power. Windows XP® and Windows® 7-compatible

software running on a PC interfaces to the TEVS board

through the computer’s USB communications port.

See the Quick Start section for setup and operating

instructions.

The EV kit daughter board provides a proven PCB layout

to facilitate evaluation of the device and must be inter-

faced to the appropriate I2C timing signals for proper

operation. See Figures 15, 16a, and 16b for connections

and appropriate voltage levels. Refer to the MAX11811

IC data sheet for timing requirements and register

addresses.

DESCRIPTION

Software and driver CD-ROM.

EV kit daughter board (with the TSC mounted on it,

but can be separated from the TEVS for evaluation

of the TSC in the user setup).

USB interface board (UTIBB+). This acts as a

1*

gateway converting and accepting data from the

USB port to I2C for the EV kit. The EV kit plugs into

the UTIBB+.

1* 4-wire touch sensor mounted with an LRA motor.

1 USB cable for power and communication.

*Mounted on a 0.125in x 3.5in x 9in Plexiglas base.
