Product details

What the 3.15A charge current and 14V input mean for the BOM

The 3.15A max charge current determines how fast a 1-cell Li-Ion pack can be charged. The 14V input maximum lets the part handle standard USB-C PD adapters without an external pre-regulator.

Lifecycle and sourcing posture

The MAX77757JEFG420+ carries an Active product status per the manufacturer's lifecycle record, with ROHS3 compliance. No end-of-life notice or last-time-buy window is in effect. If you are freezing a BOM, this part is safe for new designs today, but keep an eye on Maxim (now Analog Devices) PCNs for any future die shrinks or package changes.

Frequently asked questions

Is MAX77757JEFG420+ still active and not EOL?

Yes, the MAX77757JEFG420+ has an Active product status per the manufacturer's lifecycle record. No end-of-life notice is in effect.

Does MAX77757JEFG420+ work with USB Type-C autonomous charging?

Yes, the part is described as a 14V input, 3A USB Type-C autonomous charger — it handles the USB-C negotiation without an external host microcontroller.
