Power Managment Switch IC
BD6524HFV
No.09029EAT13
Description
Power switch for memory card Slot (BD6524HFV) is a high side switch IC having one circuit of N-channel Power MOS FET.
The switch realizes 200mΩ (Typ.) ON resistance. Operations from low input voltage (VIN ≥ 3.0V) can be made for use for
various switch applications.
The switch turns on slowly by the built-in charge pump, therefore, it is possible to reduce inrush current at switch on. There is
no parasitic diode between the drain and the source, reverse current flow at switch off is prevented. Further, it has a
discharge circuit that discharges electric charge from capacitive load at switch off.
The BD6524HFV is available in a space-saving HVSOF6 package.
Features
1) Low on resistance (200mΩ, Typ.) N-MOS switch built in
2) Maximum output current : 500mA
3) Soft start circuit
4) Under voltage lockout (UVLO) circuit
5) Discharge circuit built in : operations at switch off, UVLO
6) Reverse current flow blocking at switch off
Applications
Memory card slots of notebook PC, digital still camera, portable music player, compact portable devices such as PDA and so forth
