Datasheet Load Switch ICs 0.5A Current Load Switch ICs for Portable Equipment BD6524HFV General Description Key Specifications BD6524HFV is a high sidesw itch IC using an Input Voltage Range: 3.0V to 5.5V N-Channel MOSFET and used as a power switch for in ON-Resistance: (V =5V) 200m(Typ) IN memory card slot. This switch has an ON-Resistance (V =3.3V) 250m(Typ) IN of 200m (Typ). Operations using low input voltage Continuous Current: 0.5 A (V 3.0V) are possible for various switch Standby Current: 0.1A (Typ) IN applications. The switch turns ON slowly by the built-in Operating Temperature Range: -25C to +75C charge pump therefore, it is possible to reduce inrush current during switch ON. There is no parasitic diode between the drain and the sources o reverse current flowing at switch OFF is prevented. Furthermore, it has Package W(Typ) D(Typ) H (Max) a discharge circuit thatr eleases electric charge from capacitive load at switch OFF. This IC is available in a space-saving HVSOF6 package. Features Built in N-MOS Switch with Low ON-Resistance (200m, Typ) Maximum Output Current : 500mA Soft Start Function Under Voltage Lockout (UVLO) Protection Built in Discharge Circuit: Operations at Switch OFF, HVSOF6 UVLO 1.60mm x 3.00mm x 0.75mm Reverse Current Flow Blocking at Switch OFF Condition Applications Memory Card Slots for Notebook PC, Digital still Camera, Portable Music Player, Compact Portable Devices such as PDA and so forth.
