MAX8934D - Smart Power Selector

Download the MAX8934D datasheet PDF. This datasheet also covers the MAX8934A variant, as both devices belong to the same smart power selector family and are provided as variant models within a single manufacturer datasheet.

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.

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 for the MAX8934A/MAX8934B/MAX8934C/MAX8934E and up to 1.5mA (max) for the MAX8934D. Automatic input selection switches the system load from battery to e.

19-4995; Rev 0; 2/10 TION KIT EVALUA BLE AVAILA www.DataSheet4U.com 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.
