Load Switch ICs
0.2A, 0.5A Current Load Switch ICs
for Portable Equipment
BD2202G BD2206G
General Description
BD2202G and BD2206G are high-side switch ICs using a
single N-Channel MOSFET with low on resistance. These
ICs have over-current protection and this is triggered
when the over-current condition exceeds the
over-current shutdown time. After triggering the
over-current protection, the switch will be latched off
until enable is reset.
Moreover, soft start, under-voltage lockout, and thermal
shutdown are integrated. These ICs are used in power
supply lines of memory card slots.
