10.1 Recommended Operating Range

The maximum recommended bus voltage is lower than the absolute maximum voltage ratings on A, C, and VDD solely to provide some margin for transients on the bus. Most power systems experience transient voltages above the normal operating level. Short transients, or voltage spikes, may be clamped by the ORing MOSFET to an output capacitor and/or voltage rail depending on the system design. Transient protection, for example, a TVS diode (transient voltage suppressor, a type of Zener diode), may be required on the input or output if the system design does not inherently limit transient voltages below the TPS2412/13 absolute maximum ratings. If a TVS is required, it must protect to the absolute maximum ratings at the worst case clamping current. The TPS2412/13 will operate properly up to the absolute maximum voltage ratings on A, C, and VDD.
