Open drain output (active low). If INT is not used, tie to GND for enhanced ESD protection. Supply voltage for sensor (1.8V). To enable the device to recover from 2 VDD a high voltage system ESD strike, it is recommended to connect VDD to a host GPIO pin for independent power control. 3 GND Ground. All voltages are referenced to GND. 4 VDD3 Supply voltage for IR emitter (3.0/3.3V) 5 SCL (1) I²C serial clock input terminal 6 SDA (1) I²C serial data I/O terminal Note(s): 1. When the SDA and SCL signals are swapped, the device uses a different I²C address. See the I²C Characteristics section for more details. ams DatasheetPage 3 [v1-00] 2019-Jul-17 Document Feedback Document Outline General Description Key Benefits & Features Applications Block Diagram Pin Assignment Absolute Maximum Ratings Electrical Characteristics Timing Characteristics Detailed Description Proximity Operation Proximity I²C Characteristics Alternate I²C Address Option I²C Write Transaction I²C Read Transaction Simplified State Diagram Register Description ENABLE Register (0x80) PRATE Register (0x82) PILTL Register (0x88) PILTH Register (0x89) PIHTL Register (0x8A) PIHTH Register (0x8B) PERS Register (0x8C) CFG0 Register (0x8D) PCFG0 Register (0x8E) PCFG1 Register (0x8F) REVID Register (0x91) ID Register (0x92) STATUS Register (0x9B) PDATAL Register (0x9C) PDATAH Register (0x9D) REVID2 Register (0xA6) SOFTRST Register (0xA8) PWTIME Register (0xA9) CFG8 Register (0xAA) CFG3 Register (0xAB) CFG6 Register (0xAE) PFILTER Register (0xB3) POFFSETL Register (0xC0) POFFSETH Register (0xC1) CALIB Register (0xD7) CALIBCFG Register (0xD9) CALIBSTAT Register (0xDC) INTENAB Register (0xDD) FAC_L Register (0xE5) FAC_H Register (0xE6) TEST9 Register (0xF9) Application Information PCB Pad Layout Packaging Drawings Tape & Reel Information Soldering & Storage Information Storage Information Moisture Sensitivity Shelf Life Floor Life Rebaking Instructions Laser Eye Safety Ordering & Contact Information RoHS Compliant & ams Green Statement Copyrights & Disclaimer Document Status Revision Information Content Guide
