Description

The ISL6251, ISL6251A is a highly integrated battery charger controller for Li-Ion/Li-Ion polymer batteries and NiMH batteries. High Efficiency is achieved by a synchronous buck topology and the use of a MOSFET, instead of a diode, for selecting power from the adapter or battery. The low side MOSFET emulates a diode at light loads to improve the light load efficiency and prevent system bus boosting.

Features

• Programmable Charge Current Limit, Adapter Current Limit and Charge Voltage

• Fixed 300kHz PWM Synchronous Buck Controller with Diode Emulation at Light Load

• Output for Current Drawn from AC Adapter

• AC Adapter Present Indicator

• Fast Input Current Limit Response

• Input Voltage Range 7V to 25V

• Supports 2, 3 and 4 Cells Battery Pack
