Notes:
1. Transient surge defined in IEC60060 as a 1000 V impulse of either polarity applied to CT1–CT2 or SP1–SP2. The
shape of the impulse shall have a 300 ns full rise time and a 50 μs half fall time with 201 ? source impedance.
2. The classification currents are guaranteed only when recommended RCLASS resistors are used, as specified in
Table 10.
3. IPORT includes full operating current of switching regulator controller.
4. The PD interface includes dual-level input current limit. At turn-on, before the HSO load capacitor is charged, the
current limit is set at the inrush level. After the capacitor has been charged within ~1.25 V of VNEG, the operating
current limit is engaged. This higher current limit remains active until the UVLO lower limit has been tripped or until the
hotswap switch is sufficiently current-limited to cause a foldback of the HSO voltage.
5. See “AN296: Using the Si3400/1/2 PoE PD Controller in Isolated and Non-Isolated Designs” for more information.
6. Applies to non-isolated applications only (VOUT on schematic in Figure 1).
