15 / 44 page  Obsolete Product(s) - Obsolete Product(s) STE12PS Functional description 15/44 Figure 5. Power ON and monitoring 3.3.2 Short circuit, overload and overcurrent A short circuit is defined when port current reaches 425 mA, typ. Moreover, if port voltage drops below 25 V, then maximum loop current is decreased, linearly, to limit power dissipation. A short condition is considered as a fault after a period of 65 ms, typ. (see Table 12: Electrical characteristics, parameter Tshort). When the above conditions are met, the port is disconnected, and the fault bit set HIGH in the Channel Event registers. Overload or excess power is defined when port power consumption reaches 15.4W for longer than 65 ms, typ. (see Table 12: Electrical characteristics, parameter Tovld). If smart-power management is active, then the overload power limit is set instead - according to the power class. When the above conditions are met, the port is disconnected, and the fault bit is set HIGH. 12-bit A/D converter Digital controller D1 x12 D2 x12 STE12PS VL Px FSRPx Power On ctrl Inrushcurrent limiting SSRPx + - Power EN Short Flag RMONS RMONF HQGND AC disconnect detector ~ 50Hz 5Vpp AC_Discon flag ACSx SPx 300nF x12 Power DMOS x12 Rmon ( 500xRsense) Rsensex12 (0.5, 1, 1.5, 2 ) +48V 12-bit A/D converter 12-bit A/D converter Digital controller Digital controller D1 x12 D2 x12 STE12PS VL Px FSRPx Power On ctrl Inrushcurrent limiting SSRPx + - Power EN Short Flag RMONS RMONF HQGND AC disconnect detector ~ 50Hz 5Vpp AC_Discon flag ACSx SPx 300nF x12 Power DMOS x12 Rmon ( 500xRsense) Rsensex12 (0.5, 1, 1.5, 2 ) |
