PRODUCT DESCRIPTION
The GLF2311B-T1G7 is an advanced technology fully integrated power switch for applications required for precision output current limiting. The GLF2311B-T1G7 features also various protection functions such as under voltage lockout, true reverse current blocking (TRCB), short circuit protection, and thermal shutdown.
The GLF2311B-T1G7 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 GLF2311B-T1G7 is an ideal switch for USB power supply.
