MAX8934G Datasheet Dual-input Linear Charger Smart Power Selector

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: 19-5296; Rev 0; 6/10 .. Dual-Input Linear Charger, Smart Power Selector with Advanced Battery Temperature.

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* remendations.

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.

Key Features

  • a Smart Power Selector to make the best use of limited USB or adapter power. Input current limit and battery charge current limit are independently set. 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, respectively, while USB input current can be set to 100mA or 500mA. Automatic input selection switches the system load from battery to external power. The MAX8934G provides a SYS output voltage of 4.35V. Other features.
