Description

The MAX20353 is a highly integrated and programmablepower management solution designed for ultra-low-powerwearable applications. It is optimized for size and efficiencyto enhance the value of the end product by extending batterylife and shrinking the overall solution size. A flexible setof power-optimized voltage regulators, including multiplebucks, boost, buck-boost, and linear regulators, providesa high level of integration and the ability to create a fullyoptimized power architecture. The quiescent current ofeach regulator is specifically suited for 1µA (typ) to extendbattery life in always-on applications.The MAX20353 includes a complete battery managementsolution with battery seal, charger, power path, and fuelgauge. Both thermal management and input protectionare built into the charger.The device also includes a factory programmable buttoncontroller with multiple inputs that are customizable to fitspecific product UX requirements.Three integrated LED current sinks are included for indicatoror backlighting functions, and an ERM/LRA driver withautomatic resonance tracking is capable of providingsophisticated haptic feedback to the user.The device is configurable through an I2C interface thatallows for programming various functions and readingdevice status, including the ability to read temperatureand supply voltages with the integrated ADC.This device is available in a 56-bump, 0.5mm pitch3.71mm x 4.21mm, wafer-level package (WLP) andoperates over the -40°C to +85°C extended temperaturerange.ApplicationsWearable DevicesIoT
