ADI LTC4120EUD

多化学400mA-40°C ~ 125°C（TJ）

Overview

The LTC4120EUD is a constant-current/constant-voltage wireless receiver and battery charger. An external programming resistor sets the charge current up to 400mA. The LTC4120-4.2 is suitable for charging Li-Ion/Polymer batteries, while the programmable float voltage of the LTC4120EUD accommodates several battery chemistries. The LTC4120EUD uses a Dynamic Harmonization Control (DHC) technique that allows high efficiency contactless charging across an air gap.

Once charging is terminated, the LTC4120EUD signals end-of-charge via the CHRG pin, and enters a low current sleep mode. An auto-restart feature starts a new charging cycle if the battery voltage drops by 2.2%.
