General Description
The MAX8934G dual-input Li+/Li-Poly linear battery charger with Smart Power SelectorK safely charges a single Li+/Li-Poly cell in accordance with JEITA* recommendations. The MAX8934G monitors the battery temperature (TBATT) while charging, and automatically adjusts the fast-charge current and charge termination voltage as the battery temperature varies. The MAX8934G 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. Safety  region 2 is supported (see Figure 6 for details). An ultra-low IQ, always-on LDO provides an additional 3.3V supply for system power.
