The MAX20353 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 MAX20353 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.
