The MAX30101 provides a complete system solution to ease the design-in process for mobile and wearable devices. In common with other devices designed to make trans-cutaneous measuremetns of blood and blood flow, it has red, infrared and green emitters (LEDs).

Maxim employs a single visible-plus-infrared sensing channel. The device operates on a single 1.8V power supply and a separate 5.0V power supply for the internal LEDs. Communication is through a standard I²C-compatible interface. The module can be shut down through software with zero standby current, allowing the power rails to remain powered at all times.

Features include:

– 5.6 × 3.3 × 1.55 mm 14-pin optical module

– Integrated cover glass for optimal, robust performance

– Ultra-low power operation for mobile devices

– Programmable sample rate and LED current for power savings

– Low-power heart-rate monitor (< 1 mW)

– Ultra-low shutdown current (0.7 µA, typ)

– Fast data output capability, & high sample rates

– Robust motion artifact resilience & high SNR

– -40°C to +85°C operating temperature range
