Dual-Input Linear Chargers, Smart Power Selector with Advanced Battery Temperature Monitoring
General Description
The MAX8934_ dual-input Li+/Li-Poly linear battery chargers with Smart Power SelectorK safely charge a single Li+/Li-Poly cell in accordance with JEITA recommendations.

The MAX8934_ monitors the battery temperature (TBATT) while charging, and automatically adjusts the fast-charge current and charge termination voltage as the battery temperature varies. The MAX8934_ 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. Two safety profiles are supported (see Figure 6 for details). An ultra-low IQ, always-on LDO provides an additional 3.3V supply for system power. The MAX8934_ operates with either separate inputs for USB and AC adapter power*, or from a single input that accepts both. All power switches for charg
