The GLF2331B is an advanced technology fully integrated power switch for applications required precision output current limiting. The GLF2331B features also various protection functions such as under voltage lockout, reverse current blocking (RCB), short circuit protection, and thermal shutdown.
The GLF2331B provides a built-in output voltage slew rate control to limit the inrush current and voltage surges. The FLGB output pin can be used to send a signal of fault events to the system controller. The integrated thermal shutdown (TSD) insures complete protection for the switch during output current limit and short circuit conditions. The GLF2331B is an ideal switch for USB power supply.
