Integrated Photoplethysmogram and Electrocardiogram Bio-Sensor Module For Mobile Health General Description The MAX86150 is an integrated electrocardiogram, pulse oximeter, heart rate monitor sensor module. It includes internal LEDs, photodetector, and low-noise electronics with ambient light rejection. The MAX86150 helps ease design-in to mobile and wearable devices. The MAX86150 operates on a 1.8V supply voltage with a separate power supply for the internal LEDs. Communication to and from the module is entirely through a standard I2C-compatible interface. The module can be shut down through software with near zero standby current, allowing the power rails to remain powered at all times. ●● Electrocardiogram (ECG) Optimized for Dry Electrode Operation ●● Reflective Heart Rate Monitor and Medical-Grade Pulse Oximeter ●● Miniature 3.3mm x 5.6mm x 1.3mm 22-pin Optical Module • Optical-Grade Glass for Long-Term Optimal and Robust Performance ●● Ultra-Low Power Operation for Mobile Devices • Ultra-Low Shutdown Current (0.7μA Typical) ●● High SNR and Robust Ambient Light Cancellation ●● -40°C to +85°C Operating Temperature Range Ordering Information appears at end of data sheet. ●● Fitness Assistant Devices Simplified Block Diagram HOST (AP) DIGITAL NOISE CANCELLATION HARDWARE FRAMEWORK ALGORITHMS DRIVER DATA FIFO HUMAN FINGER RED/IR LEDS AMBIENT LIGHT CANCELLATION AMBIENT LIGHT PACKAGING ELECTRODES
