Key Features
- Integrated Li-ion battery charger, fuel gauge, and ultra-low IQ regulators in a single PMIC
- 8 configurable power management channels with adjustable output thresholds
- Ultra-compact 56-ball WLCSP (7x8 grid) for minimal footprint in wearable designs
- Ultra-low quiescent current optimized for extended battery runtime in always-on IoT nodes
- Introduced in 2017 with 9-year estimated lifecycle for wearable production programs
Applications
The MAX20303LEWN+T is designed for small Li-ion-powered wearables, hearables, and compact IoT devices where board space and battery life are the primary design constraints. Its integrated charger, fuel gauge, and multiple voltage regulator channels consolidate what would otherwise require 3–5 separate ICs into a single 56-ball WLCSP, enabling sub-centimeter power management in fitness trackers and medical patches.

Frequently Asked Questions
How many independent power rails can the MAX20303LEWN+T supply in a wearable system, and are they individually adjustable?
The MAX20303LEWN+T provides 8 power management channels with individually adjustable output voltage thresholds, allowing designers to configure separate rails for the application processor, sensor subsystem, radio, and display from a single 56-ball WLCSP PMIC without discrete regulators for each supply.
What is the advantage of an integrated fuel gauge in MAX20303LEWN+T versus a discrete gas gauge IC for wearable designs?
An integrated fuel gauge eliminates a separate gas gauge chip such as a MAX17048 or similar, saving at least 1 IC, reducing BOM cost, and freeing PCB area in the tight 56-ball WLCSP footprint. The on-chip gauge shares the I2C bus and Li-ion charger state, enabling tighter charge/discharge control without inter-IC communication latency.
Is the 56-ball WLCSP package on MAX20303LEWN+T compatible with standard PCB assembly processes used for wearables?
The MAX20303LEWN+T uses a 56-ball WLCSP in a 7x8 grid with 20 µm ball pitch, which requires fine-pitch solder paste stenciling and reflow assembly capabilities. Most contract manufacturers specializing in wearable or medical device PCBs support this pitch, but buyers should confirm their SMT partner's WLCSP assembly qualifications before committing to volume production.
When evaluating MAX20303JEWN+T versus MAX20303LEWN+T, what is the key difference between these two variants?
Both the MAX20303JEWN+T and MAX20303LEWN+T share the same 56-ball WLCSP package and 8-channel PMIC architecture. The J and L designators in Analog Devices part numbering typically distinguish temperature grade or minor feature variants; designers should consult the datasheet for each variant to confirm exact parameter differences before selecting one for production.
