MAX20366AEWZ+T

MAX20366AEWZ+T is the tape-and-reel order code for the Analog Devices MAX20366 wearable PMIC in a 72-bump wafer-level package (0.5 mm pitch, 4.88 x 4.19 mm), rated -40 to +85 deg C — a complete power and battery subsystem for smartwatches, fitness bands and other small Li+ powered wearables. One device integrates two 400 mA micro-IQ buck regulators (330 nA typical quiescent current each), a 600 mA micro-IQ buck, a micro-IQ buck-boost, a boost regulator for display rails, LDO/load switches, a full battery solution (charger with JEITA profiles on a 28 V tolerant input, power path, battery seal and ModelGauge fuel gauge), three LED current sinks, an ERM/LRA haptic driver with automatic resonance tracking, and a programmable push-button controller — all configured over I2C with an on-chip ADC for voltage and charge-current monitoring. Replacing a discrete power tree with this single PMIC is the selection point: it shrinks solution size and extends standby time in always-on products. Selection advice: quote the full MAX20366AEWZ+T code for tape-and-reel supply (MAX20366AEWZ+ is the same device without the reel suffix), and confirm the required factory-programmed options, such as the push-button controller configuration, when ordering. Parameters verified against the Analog Devices official datasheet (19-101944, Rev 1, ordering information).
