MAX20360 PMIC with Ultra-Low I Regulators, Charger, Q Fuel Gauge, and Haptic Driver for Small Li+ System General Description Benefits and Features The MAX20360 is a highly integrated and programmable Extend Battery-Use Time Between Battery Charging power management solution designed for ultra-low-power 2 x Micro-I , 400mA Buck Regulators (330nA I Q Q wearable applications. It is optimized for size and efficien- typ each) cy to enhance the value of the end product by extending 0.550V to 1.180V in 10mV Steps battery life and shrinking the overall solution size. A flex- 0.550V to 2.125V in 25mV Steps ible set of power-optimized voltage regulators, including 0.550V to 3.700V in 50mV Steps multiple buck, boost and buck-boost converters, and lin- Micro-I , 600mA Buck Regulator (330nA I typ) Q Q ear regulators, provides a high level of integration and the 0.550V to 1.180V in 10mV Steps ability to create a fully optimized power architecture. The 0.550V to 2.125V in 25mV Steps quiescent current of each regulator is ultra-low targeted at 0.550V to 3.700V in 50mV Steps extending battery life in always-on applications. Micro-I LV LDO/Load Switch (1A I typ) Q Q The MAX20360 includes a complete battery management 1.0V to 2.0V Input Voltage solution with battery seal, charger, power path, and fuel 50mA Output gauge. Both thermal management and input protection 0.5V to 1.95V Output, 25mV Steps are built into the charger. The device also includes a facto- Micro-I LDO/Load Switch (1A I typ) Q Q ry programmable button controller with multiple inputs that are customizable to fit specific product UX requirements. 1.71V to 5.5V Input Voltage 100mA Output Three integrated LED current sinks are included for indica- 0.9V to 4V, 100mV Steps tor or backlighting functions, and an ERM/LRA driver with Micro-I Buck-Boost Regulator (2A I typ) Q Q automatic resonance tracking is capable of providing so- phisticated haptic feedback to the user. A low noise, 1.5W 1.5W Output buck-boost converter provides a clean way to power LEDs 2.6V to 5V in 50mV Steps commonly used in optical heart-rate systems. The device Easy-to-Implement Li+ Battery Charging 2 is configurable through an I C interface that allows for pro- Wide Fast Charge Current Range: 5mA to 500mA gramming various functions and reading the device status, 28V/-5.5V Tolerant Input including the ability to read temperature and supply volt- Programmable JEITA Current/Voltage Profiles ages with the integrated ADC.
