The LTC4124 is a simple high performance wireless Li-Ion charger with low battery disconnect. The pin-selectable charge current (up to 100mA) and charge voltage ensure versatility while minimizing the number of required external components.
Wireless charging with the LTC4124 allows devices to be charged while sealed within enclosures and eliminates bulky connectors in space-constrained applications. Elimination of exposed conductive connectors also creates more robust devices while ensuring an effortless end-user experience.
The LTC4124 includes an NTC input for safe temperature qualified charging and a battery disconnect feature that prevents damage to a battery due to over-discharging.
The 2mm × 2mm LQFN package and minimal number of external components make the LTC4124 well-suited for low power portable applications where small solution size is mandatory.

Despite showing available on the website and accepting my order, they called to tell me that the order was not available.
I had to then concede with another lower rated battery.
The issue doesn't end here.
I was supposed to get a refund for the difference in pricing, but despite reminders and calls (which were not answered), I didn't get any refund until I almost filed a police complaint against them.
