Detailed Description
A fully integrated proximity detection solution is provided with an 850-nm IR LED, LED driver circuit, and
proximity detection engine. An internal LED driver (LDR) pin, is connected to the LED cathode (LEDK) to provide
a factory calibrated proximity of 100 mm, ± 20 mm. This is accomplished with a proprietary current calibration
technique that accounts for all variances in silicon, optics, package, and most important, IR LED output power.
This eliminates or greatly reduces the need for factory calibration that is required for most discrete proximity
sensor solutions. While the device is factory calibrated at a given pulse count, the number of proximity LED
pulses can be programmed from 1 to 255 pulses, which allows different proximity distances to be achieved.
Each pulse has a 16 μ s period, with a 7.2 μ s on time.
The device provides a separate pin for level-style interrupts. When interrupts are enabled and a pre-set value
is exceeded, the interrupt pin is asserted and remains asserted until cleared by the controlling firmware. The
interrupt feature simplifies and improves system efficiency by eliminating the need to poll a sensor for a proximity
value. An interrupt is generated when the value of a proximity conversion exceeds either an upper or lower
threshold. In addition, a programmable interrupt persistence feature allows the user to determine how many
consecutive exceeded thresholds are necessary to trigger an interrupt.
