R5542 Typical Application
Battery line switch IC can suppress inrush current at start-up by its soft-start circuit. Due to the reverse current protection function during off state or for always, unlike a simple MOSFET, space saving is possible to realize intensive functions.
They are used as load switches. To use the R5527 as a load switch, discharge function can be selected as an option. Further, the R5542 has another voltage detector inside.
