SX8657/SX8658
Haptics Enabled 4/5-Wire
Resistive Touchscreen Controller with Proximity Sensing
GENERAL DESCRIPTION
The SX8657 and SX8658 belong to a family of high
performance haptics enabled 4/5-wire resistive touch
screen controller with proximity detection, optimized
for hand held applications such as mobile phones,
portable music players, game machines, point-of-
sales terminal and other consumer and industrial
applications. They feature a wide input supply range
from 2.3V to 3.6V.
The
controller
computes
touch
screen
X-Y
coordinates and touch pressure with a precision, low
power 12-bit analog-digital converter.
On-chip data
averaging processing algorithms can be activated to
reduce host activity and suppress system noise. The
processing core features low power modes which
intelligently minimize current in operation as well as in
automatic shut-down.
A capacitive proximity detection circuit has been
integrated into the SX8657 to enable host controlled
power management for battery applications. Proximity
detection above 5 cm is possible using either the
resistive touch screen as the sensor or with a single
conductive plate, with communication to the host via
the serial interface.
The SX8657 and SX8658 also integrate a haptics
motor driver for Linear Resonant Actuator (LRA) and
Eccentric Rotating Mass (ERM) micro motors with up
to 250mA drive current.
Haptics control can be
performed using either an external PWM signal or the
I2C serial interface, providing simple host interfacing
and minimizing its I/O requirement. The SX8657/58
supports Immersion
TouchSense 3000 haptic
control software for high quality touch feedback.
Integrated very high ESD protection, of up to ±15kV
on display inputs not only saves cost and board area,
but also increases application reliability.
The three devices have an ambient operating
temperature range of -40°C to +85°C, and are offere d
in both a 4mm x 4mm, 20-lead QFN package and
2.07mm x 2.07mm 19-lead CSP package for space-
conscious applications.
