VD5376
Ultra-low power motion sensor
for Optical Finger Navigation (OFN) and optical/laser mice
Data brief
Features
Ultra-low power performance and high
speed/high accuracy motion detection
(1 m/s, 20 g)
Optional on-chip power management scheme
(RUN/IDLE1/IDLE2/SLEEP)
Very low quiescent and operating current mode
for battery life saving
CPI programmable up to 3,200 CPI
On-chip boost-converter controller enables a
complete autonomous single AA/AAA-type
battery supply application
I2C interface, with fast polling rate capability for
high end applications (report rate up to 1 per
millisecond)
Internal oscillator
On-chip ADC for battery level reporting
Laser drive circuitry, fault detection scheme
and safety features
Versatile usage: the sensor is designed to
operate with a companion microcontroller, and
can be used for any laser/LED mouse system
Minimal external component requirement
Miniature die enabling smallest modules
Module design support
Description
This device is intended to fit into any two-chip
applications (companion MCU) and offers the
best compromise between application cost, power
and performance.
It is ideally suited to meet requirements of the
growing number of devices using finger navigation
as an easy and intuitive human interface method.
