ISL29021IROZ-T7 Optical Sensor IR I²C 8-WFDFN Exposed Pad 2.25V ~ 3.63V

ISL29021IROZ-T7 Optical Sensor IR I²C 8-WFDFN Exposed Pad Light To Digital Converters

The ISL29021 is an integrated proximity and infrared sensor with a built-in IR LED driver and I2C Interface (SMBus Compatible). This device provides infrared sensing to allow proximity estimation featured with interrupt function. For infrared and proximity sensing, an internal ADC has been designed based on the charge-balancing A/D conversion technique. The ADC is used to digitize the output signal from the photodiode array when the internal IR LED driver is turned on and off for the programmed time periods under user-selected modulation frequency to drive the external IR LED. As this proximity sensor employs a noise cancellation scheme to highly reject unwanted IR noise, the digital output of proximity sensing decreases with distance. The driver output current is user selectable up to 100mA to drive different types of IR emitters LEDs. Four different modes of operation can be selected via the I2C interface: programmable IR sensing once, programmable proximity sensing once, programmable continuous IR sensing and programmable continuous proximity sensing. The programmable one-time operation modes greatly reduce power because an immediate automatic shutdown reduces overall supply current less than 0.5µA. The ISL29021 supports both hardware and software interrupts that remain asserted until the host clears it through I 2C interface for proximity detection. Designed to operate on supplies from 2.5V to 3.63V, the ISL29021 is specified for operation over the -40°C to +85°C ambient temperature range. It is packaged in a clear, Pb-free 8 Ld ODFN package.
