The MAX20303 is a highly integrated and programmable power management solution designed for ultra-low-power wearable applications. It is optimized for size and efficiency to enhance the value of the end product by extending battery life and shrinking the overall solution size. A flexible set of power-optimized voltage regulators, including multiple bucks, boost, buck-boost, and linear regulators, provides a high level of integration and the ability to create a fully optimized power architecture. The quiescent current of each regulator is specifically suited for 1µA (typ) to extend battery life in always-on applications.
The MAX20303 includes a complete battery management solution with battery seal, charger, power path, and fuel gauge. Both thermal management and input protection are built into the charger.
The device also includes a factory programmable button controller with multiple inputs that are customizable 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 is capable of providing sophisticated haptic feedback to the user.
The device is configurable through an I2C interface that allows for programming various functions and reading device status, including the ability to read temperature and supply voltages with the integrated ADC.
This device is available in a 56-bump, 0.5mm pitch 3.71mm x 4.21mm, wafer-level package (WLP) and operates over the -40°C to +85°C extended temperature range.
