Note: Connect the circuits A and B in parallel to produce a low ON resistance (R
ON
= 0.06
). In
this case, connect the DLYA and DLYB pins in common to give synchronous ON/OFF
between both switches.

Notes:
1.
Make this connection to produce an ON resistance that is much lower than the above connection.
Also, connect the DLY pins in common.
Consider the difference between the ON resistances and the switch-ON/OFF times between two
devices (MB3802) and insure that load control is not offset at one device.
