BH1792GLC-E2 ROHM, Through Hole Reflective Sensor, Photodiode Output, WLGA010V28 package

BH1792GLC is optical sensor for heart rate monitor IC in which LED driver, green light and IR detection photodiode are incorporated. This device drives LED and provides the intensity of light reflected from body. LED brightness can be adjusted by LED driver current. The photodiode having the high sensitivity for green light and excellent wavelength selectivity achieves accurate pulse wave detection.

Build-in green photodiode with excellent wavelength
selective green filter and IR curt filter.
Built-in IR photodiode for touch detection.
Correspond to high sampling frequency. (1024Hz)
LED driver with current selection.
I2C bus Interface(f/s mode support)
Built-in FIFO
Applications
Wearable device, smart phone, Tablet PC.
