I(ref) x C x R(IS12) = R(sense) x I(OCP_Trip)
I(OCP_Trip) = 20 A x 8 x 560 /0.01 = 9.2 A
C = Current ratio (see recommended operating conditions)
Overvoltage Protection
The overvoltage protection (OVP) of the TPS3513 monitors 3.3 V, 5 V, and 12 V. When an overvoltage condition
appears at one of the 3.3-V, 5-V, or 12-V input pins for more than 73 s, the FPO output goes high and PGO
goes low. Also, this fault condition will be latched until PSON is toggled from low-to-high or VDD is removed.
During fault conditions, most power supplies have the potential to deliver higher output voltages than those
normally specified or required. In unprotected equipment, it is possible for output voltages to be high enough to
cause internal or external damage of the system. To protect the system under these abnormal conditions, it is
common practice to provide overvoltage protection within the power supply.

Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating
conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
