MAX8934BETI+規(guī)格書詳情

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.
