ISL6257 Overview
Key Features
- 5% per cell to optimize battery capacity. When supplying the load and battery charger simultaneously, the input current limit for the AC adapter is programmable to within ±3% accuracy to avoid overloading the AC adapter and to allow the system to make efficient use of available adapter power for charging. It also has a wide range of programmable charging current. The ISL6257 automatically transitions from regulating current mode to regulating voltage mode
- ±0.5% Charge Voltage Accuracy (-10°C to +100°C) ±3% Accurate Input Current Limit ±3% Accurate Battery Charge Current Limit ±25% Accurate Battery Trickle Charge Current Limit Programmable Charge Current Limit, Adapter Current Limit and Charge Voltage Fixed 300kHz PWM Synchronous Buck Controller with Diode Emulation at Light Load AC Adapter Present Indicator Fast Input Current Limit Response Input Voltage Range 7V to 25V Support 2, 3 and 4 Cells Battery Pack Up to 17.64V Battery-Voltage Set Point Control Adapter Power S
