Analog Devices Inc. MAX20366 PMIC

The ADI MAX20366 combines a flexible set of power-optimized voltage regulators, including multiple buck, boost, buck-boost converters, and linear regulators. This combination delivers a high level of integration and allows for the creation of a fully optimized power architecture. Each regulator's ultra-low quiescent current extends battery life in always-on applications.

The MAX20366 includes a complete battery management solution with a battery seal, charger, power path, and fuel gauge. The charger has thermal management and input protection built-in. The device also includes a factory-programmable button controller with multiple customizable inputs to fit specific product UX requirements.

Three integrated LED current sinks are included for indicator or backlighting functions, and an ERM/LRA driver with automatic resonance tracking can provide refined haptic feedback to the user. A low-noise, 1.5W buck-boost converter supplies a clean way to power LEDs commonly used in optical heart-rate systems. The ADI MAX20366 is configurable via an I2C interface that allows for programming various functions and reading the device status, including the ability to read temperature and supply voltages with the integrated ADC.

The device is housed in a 72-bump, 0.5mm pitch, 4.88mm x 4.19mm, wafer-level package (WLP) and operates at an extended temperature range of -40°C to +85°C.
