产品概述

The MAX8934DETI+ is a dual-input linear charger, Smart Power Selector with advanced battery temperature monitoring in 28 pin TQFN package. MAX8934 device monitors battery temperature (TBATT) while charging and automatically adjusts the fast-charge current and charge termination voltage as the battery temperature varies. It also monitors the battery temperature while the battery is discharging and provides a warning flag (OT) to the system in the event that the battery is over temperature. It operates with a separate input for USB and AC adapter power or from a single input that accepts both. All power switches for charging and switching the load between battery and external power are included on-chip. Input power not used by the system charges the battery. Charge current limit and DC current limit can be set up to 1.5A and 2A. This device is typically used for open-drain charge status and fault outputs, power-OK monitors, charge timer applications.
  • Safely charges a single Li+/Li-Poly cell in accordance with JEITA recommendations
