BH1790GLC-Optical-Hearts-Rate-Sensors

BH1790GLC Optical Heart Rate Sensor ICs

The BH1790GLC is an optical heart rate sensor IC, used for heart monitoring. It incorporates an LED driver and green light detection photo-diode.


This innovative device drives the LED, providing intensity of light reflected from the body.


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


The photodiode has a high sensitivity for the green light, excellent wavelength selectivity and first rate Ircut characteristics, achieving highly accurate pulse wave detection.

Key Features

  • Green filter with excellent wavelength selectivity
  • Built-in Ircut filter
  • LED Driver with current selection
  • Corresponds to 1.8V I2C Interface
