DESCRIPTION
FEATURES
A built-in charge pump is used to drive the N-channel NMOSFET that is free of parasitic body diode to eliminate any reversed current flow across the switch when it is powered off.● 100mΩ (Typ.) High-Side NMOSFET (SOT-25)
● 1.1/1.3A Current Limit
● Small SOT-25 Package Minimizes Board Space
● Soft Start
● Thermal Protection
● Low 23μA Supply Current
● Wide Input Voltage Range: 2.2V ~ 6V
● Available in SOT-25 package APPLICATION Several protection functions include soft start to limit inrush current during plug-in, current limiting at 1.1/1.3A to meet USB power requirement, and thermal shutdown to protect damage under over current conditions.
● Battery-Powered Equipment
● Motherboard USB Power Switch
