ISL6298-2CR3 Datasheet, PDF (3/17 Pages) Intersil Corporation – Li-ion/Li-Polymer Battery Charger

ISL6298
Electrical Specifications
Typical values are tested at VIN = 5V and 25°C Ambient Temperature, maximum and minimum values are
guaranteed over 0°C to 70°C Ambient Temperature with a supply voltage in the range of 4.3V to 6.5V, unless
otherwise noted. (Continued)
