SLVSFE3B November 2020 – May 2021 TPS2661
The TPS2661x devices provide protection from over-voltage events on OUT pin by turning off the internal Pass FETs and cutting off the signal path whenever VOUT goes above VOUT_OVLO threshold. The signal path through TPS2661x is restored again when VOUT goes below [VOUT_OVLO - VOUT_OVLO_Hyst] value. The device turns off the internal FETs within a time of tOUT_OV_CUT after output voltage has gone above VOUT_OVLO threshold. See Timing Requirements in Specifications for tOUT_OV_CUT.The device recovers from output over-voltage within a time of tOUT_CUT_Rec after output voltage has gone below [VOUT_OVLO ‒ VOUT_OVLO_Hyst] value. See Timing Requirements in Specifications for tOUT_OV_CUT. Figure 8-9 illustrates the output over-votlage protection in TPS2661x devices.
