BD6524HFV
General Description
BD6524HFV is a high side switch IC using an
N-Channel MOSFET and used as a power switch for in
memory card slot. This switch has an ON-Resistance
of 200mΩ (Typ). Operations using low input voltage
(VIN ≥ 3.0V) are possible for various switch
applications. The switch turns ON slowly by the built-in
charge pump; therefore, it is possible to reduce inrush
current during switch ON. There is no parasitic diode
between the drain and the source so reverse current
flowing at switch OFF is prevented. Furthermore, it has
a discharge circuit that releases electric charge from
capacitive load at switch OFF. This IC is available in a
space-saving HVSOF6 package.
