BH1790GLC - Optical Sensor

Description

BH1790GLC is optical sensor for heart rate monitor IC in which LED driver and green light detection photo-diode are incorporated.

This device drives LED and provides the intensity of light reflected from body.

LED brightness can be adjusted by LED driver current and light emitting period.

Features

  • Green filter with excellent wavelength selectivity.
  • Built-in Ircut Filter.
  • LED driver with current selection.
  • Correspond to 1.8V I2C Interface. Package W(Typ) x D(Typ) x H(Ma.
