Product details

The Maxim Integrated MAX8903CETI+ is a 1-cell Lithium-Ion battery charger IC from the Smart Power Selector™ series. It handles a single Li-Ion cell with a programmable constant-current charge up to 2A, fed from a USB or adapter input rated up to 16V. The 28-TQFN (4x4 mm) package with exposed pad keeps thermal transfer honest for the 2A charge rate — the pad needs a solid via array to the ground plane if you plan to run near the limit.

Sourcing and lifecycle

It is RoHS3 compliant. No end-of-life notice is on record.

Frequently asked questions

What is the MAX8903CETI+ maximum charge current?

The maximum charge current is 2A, programmable via an external resistor. This is a constant-current charge profile for a single Li-Ion cell.

Does MAX8903CETI+ support fast charging?

Yes — the charge current is programmable up to 2A, which qualifies as fast charging for a single Li-Ion cell. The constant-current profile is adjustable via an external resistor.

Where can I buy MAX8903CETI+ available via RFQ confirmation?

This part is available to order through independent distribution. Pricing and stock levels are confirmed at the time of quote — submit an RFQ for current availability and lead time.

Does MAX8903CETI+ have an equivalent or replacement?

No direct pin-compatible replacement is listed in the official records. For a same-function alternative within the Smart Power Selector™ family, review other 1-cell Li-Ion charger ICs from Maxim with similar package and charge current ratings.
