MAX11835 Evaluation System
Evaluates: MAX11835
General Description
The MAX11835 evaluation system (EV system)
demonstrates a complete solution to drive single and
multilayer piezo actuators to create haptic feedback
for products featuring touch interfaces. The MAX11835
efficiently generates any type of user-programmable
waveforms including sine, trapezoidal, square, and
pulse to drive the piezo loads to create custom haptic
sensation. The low-power device directly interfaces
with an application processor/host controller through an
I2C interface and integrates various blocks including a
boost regulator, pattern storage memory, and waveform
generator in one package, thus providing a complete
haptic feedback controller solution.
The EV system is a multiboard system that includes a
MAXQ2000 USB touch interface board (UTIB) and a
MAX11835 daughter board.
Note: The CD-ROM included with the EV kit contains
a User’s Guide that provides information about the
graphical user interface (GUI).
Note: The MAX11835 is not a touch-screen control-MAX11835 is not a touch-screen control-
ler and the touch panel is only provided for haptic
feedback purposes, with the 4-wire flex connector left
unconnected.
