Product details

Smart Power Selector Li-Ion charger for portable designs

The MAX8903AETI+ from Analog Devices is a single-cell Li-Ion battery charger IC belonging to the Smart Power Selector series. It handles a constant-current programmable charge up to 2A, fed from a USB interface, and targets portable equipment where the system load can be powered directly from the charger while the battery charges independently. The 28-TQFN (4x4 mm) package with exposed pad keeps the thermal path short for the 2A charge current. Operating over -40°C to 85°C, it suits industrial handhelds, medical monitors, and outdoor IoT nodes that see temperature swings.

Active lifecycle — no LTB pressure

The MAX8903AETI+ carries an active lifecycle status, so there is no last-time-buy clock running. It is ROHS3 compliant, which matches current assembly requirements. For BOM planners: no PCN watch needed yet; this part is a stable line item for new designs and production runs. Sourced through independent distribution, availability and current pricing are confirmed at quote time against an RFQ.

Frequently asked questions

What is the charge current for MAX8903AETI+?

The MAX8903AETI+ supports a programmable constant charge current up to 2A max for a single Li-Ion cell.

Is MAX8903AETI+ obsolete or active?

The MAX8903AETI+ is active in production with no end-of-life notice. It is ROHS3 compliant.

Where can I buy MAX8903AETI+?

This part is sourced and quoted to order through independent distribution. Submit an RFQ for current availability and pricing.

What is the pinout of MAX8903AETI+?

The MAX8903AETI+ is packaged in a 28-TQFN (4x4 mm) with exposed pad. The pinout is defined in the official datasheet; key pins include USB input, battery output, charge-current program resistor, timer capacitor, and status indicators.

What is the equivalent or replacement for MAX8903AETI+?

Within the Smart Power Selector family, the MAX8903AETI+ is a specific variant. For a direct pin-compatible alternative, verify the exact suffix; the MAX8903BETI+ differs in charge-current programming method. Confirm the specific feature set needed for your design.

What is the maximum charge current for MAX8903AETI+?

The maximum charge current is 2A, programmable via an external resistor.

Is MAX8903AETI+ compatible with USB 2.0?

The charger accepts input from a USB interface (5V nominal). It includes over-voltage fault protection, which helps handle the 5V USB bus. Compatibility with USB 2.0 depends on the host controller and cable; the charger itself does not negotiate USB data rates.
