ISL6291 - Li-ion/Li Polymer Linear Battery Charger
VIN (Pin 1, 15, 16) VIN is the input power source pin that is connected to a wall adapter.
V2P8 (Pin 8) V2P8 is a 2.8V reference voltage output.
V2P8 pin outputs a 2.8V voltage when the input voltage rises above the POR threshold and outputs zero voltage otherwise.
This pin can be used as an adapte
® ISL6291 Data Sheet November 2003 FN9102.1 Li-ion/Li Polymer Linear Battery Charger The ISL6291 provides a low-cost integrated charger solution for single-cell Li-ion and Li Polymer rechargeable batteries.
No external pass element, current sensing resistor, or reverse blocking diode is required with this solution.
The ISL6291 is a constant-current (CC)/constant-voltage (CV) charger.
The constant charge current is programmable up to 2.0A with an external signal resistor.
