2.0A Current Load Switch ICs
for Portable Equipment
BD6520F BD6522F
General Description
BD6520F and BD6522F are power management
switches (N-Channel Power MOSFET) with an ON-
Resistance of 50mΩ (Typ). An internal charge pump
drives the gate of the N-Channel Power MOSFET. Also,
an external capacitor can be connected to the soft start
control terminal, thus achieving reduction of the inrush
current to the load capacitor during turn on.
Furthermore, these ICs have undervoltage lockout,
thermal shutdown and a discharge circuit for the
capacitive load at switch OFF.

Caution: Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit
between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated
over the absolute maximum ratings.
