HX3001LB最新原厂规格书.pdf

TEL ICQ:3445216498 Product Definition 4:LD- 3:VOUT Ultra-low power, small size optical In-Ear Sensor for wearable applications Description HX300 LB is an ultra-low power optical sensor for In-Ear for wearable devices HX300 LB can fit into ultra-compact wearable devices such as Smart earphone because of its ultra-small size. HX300 LB include both optical( transmitter and receiver ) 1:LD+ 2:VCC and ASIC, ASIC control light transmitter and calculate the light who is reflected back by obstacle, The transmitter supports LD The Receiver have photo diode, In-Ear measures signal at with DC cancellation scheme to monitor . The proximity sensing , a proximity detection photo diode, when receive the feedback of light from LD . The current from the VO pin to ground by resistor, the more light, the more current , master can judge by voltage of the resistor who between VO pin to ground. ASIC delete the noise of sunshine HX300 LB has optimized low power performance, proximity in-ear detection. Features  ASIC low power, delete the noise  Operating Temperature Range: -20℃ to 85℃  Low power dissipation  LD MAX current from 12mA  Package size :2mm×1.6mm×0.7mm Applications  Earphone  Smart wearable device TYHX Confidential
