MinE-CAP differential voltage across C , the MinE-CAP IC regulates the voltage LV across C to within a predetermined range (V ). This ensures LV TRKLCHRG that during line dropout or load step, there is no impact on the power Begin Steady-State supply power deliver capability. The MinE-CAP IC is designed with extremely low off-state leakage current, much lower than the self-leakage current of C , to ensure that the voltage across C does LV LV not accumulate over time. YesBrown-OutVTOP > VCOV? If the bulk voltage fal s below I for ~500 ms the control er resets UV- and undergoes a normal start-up sequence. Fault HandlingDisable MinE-CAP The MinE-CAP IC has built-in the fol owing fault detection capabilities. Power SwitchNo Fault communication to InnoSwitch is done via the LINE pin. NoSurgeEnable MinE-CAP The MinE-CAP IC has surge detection capability. If the power switch Power Switch is on and a surge event occurs, the power switch is disabled for 130 ms. NoVTOP < VCOV? After the ~130 ms timer expires, the MinE-CAP IC returns to steady- state operation. Surge information is not communicated to the InnoSwitch IC. YesOver-Temperature Protection The MinE-CAP IC has thermal detection circuitry to maintain the YesVBOT~= 0 V? MinE-CAP temperature below a safe level. In the event the MinE-CAP PI-9215-082020 temperature exceeds T the part goes into thermal shutdown and SD I is injected into the V pin of InnoSwitch IC. Once the INJECT(OV) MinE-CAP temperature fal s below T , the MinE-CAP control er is SD(H) reset and undergoes a normal start-up sequence. Figure 7. Steady-State MinE-CAP Power Switch Control. Pin Open/Short Faults The MinE-CAP IC has pin open/short detection on VBOT and DRAIN Trickle Charge Regulation pins. In the event of a pin fault, I is injected into the V pin of INJECT(OV) During system conditions where the DC bus voltage constantly InnoSwitch until the fault is removed. Subsequently, the MinE-CAP remains above V , e.g. during light load condition, the MinE-CAP IC control er is reset and undergoes a normal start-up sequence. COV+ uses trickle charging algorithm to ensure there is sufficient charge on C to support power delivery if required. By measuring the LV 5 Rev. D 11/20 www.power.com
