Key Features
- Integrates battery charger, fuel gauge, and 8 ultra-low IQ voltage regulator channels in a single 56-bump WLCSP die for minimal BOM count in wearable designs
- Ultra-low quiescent current extends battery runtime in always-on IoT and wearable applications where standby power must remain below 10 µA
- 56-bump WLCSP package with 0.40 mm bump pitch fits in board footprints under 4 mm × 4 mm, ideal for space-constrained smartwatch and hearable PCBs
Applications
The MAX20303KEWN+T is purpose-built for wearables, hearables, and compact IoT devices powered by a single-cell Li-ion battery, where integrating charging, fuel gauging, and multiple regulated rails into one IC eliminates the need for discrete PMIC components. Its ultra-low quiescent current and small WLCSP footprint make it well suited for continuous health-monitoring devices, smart patches, and miniature wireless sensors requiring multi-day battery life from a sub-100 mAh cell.

Frequently Asked Questions
How many regulated output channels does the MAX20303KEWN+T provide, and what is the typical quiescent current?
The MAX20303KEWN+T provides 8 regulated output channels integrating multiple buck and LDO regulators, with total system quiescent current typically below 10 µA in standby, enabling multi-day operation from a 50 mAh to 100 mAh Li-ion cell in wearable applications.
What is the package type and footprint of the MAX20303KEWN+T, and how does it fit into a compact PCB design?
The MAX20303KEWN+T uses a 56-bump WLCSP (wafer-level chip-scale package) with 0.40 mm bump pitch, occupying a die footprint under 4 mm × 4 mm. This allows placement on single-layer flexible PCBs or multi-layer rigid boards in smartwatch modules as thin as 1 mm.
When is the MAX20303KEWN+T a better choice than separate charger, fuel gauge, and regulator ICs for a wearable design?
When PCB area is constrained below 100 mm² and BOM cost reduction is a priority, the MAX20303KEWN+T replaces 3 or more discrete ICs with a single 56-bump WLCSP, cutting total solution area by more than 50% compared to a discrete charger plus fuel gauge plus 8-channel regulator solution.
Which Li-ion battery chemistries and charge voltage levels are supported by the MAX20303KEWN+T charger?
The MAX20303KEWN+T battery charger supports standard single-cell Li-ion and Li-polymer cells with a charge termination voltage of 4.2 V, and is configurable for cells up to 4.35 V. Charge current is programmable from 8 mA to 300 mA to match cell capacities from 25 mAh to 150 mAh used in compact wearables.
