Port capacitor: Connect a 220 nF–470 nF, 100-V,
X7R ceramic capacitor from Px to Nx.
Fuse: The port fuse must be a slow blow type
rated for at least 60 VDC and 1 A. A resettable Polyfuse can also be used.
Protection Diodes: The port TVS must be rated for
the expected port surge environment. The TVS must have a minimum reverse
standoff voltage of 58 V and a maximum clamping voltage of 95 V at the expected
peak surge current. The negative clamp diode must be rated for VR =
100-V minimum and be able to survive the expected negative surge current. Low
forward voltage drop at the rated current is essential.
Integration capacitor: Connect a 0.027-μF, 16-V
minimum, polycarbonate, poly-polypropylene,
polystyrene, teflon, or other low leakage
capacitor from CINTx to RG as close to the device
as possible.
