Manufacturer:NS Description:The LTC®4055 is a USB power manager and Li-Ion battery charger designed to work in portable battery-powered applications. The part manages and limits the total current used by the USB peripheral for operation and battery charging. Depending on the state of the current select pin (HPWR), total input current can be limited to either 100mA or 500mA. The voltage drop from the USB supply or battery to the USB peripheral is typically less than 100mV at 400mA and 20mV at 80mA. Other management features include: automatic switch over to battery when input is removed, inrush current limiting, reverse current block- ing, undervoltage lockout and thermal shutdown. |
