8 / 28 page  5.6 Electrical Characteristics (continued) over operating junction temperature range (unless otherwise noted) PARAMETER TEST CONDITIONS MIN TYP MAX UNIT TSD_RISING The rising over-temperature protection shutdown threshold 150 175 °C TSD_FALLING The falling over-temperature protection shutdown threshold 130 140 °C TSD_HYST The over-temperature protection shutdown threshold hysteresis 35 °C 5.7 Timing Requirements MIN NOM MAX UNIT Power-On and Off Timings tON_FET Time from Crossing Rising VPWR UVLO until CC and SBU OVP FETs are on. 1.3 3.5 ms tON_FET_DB Time from Crossing Rising VPWR UVLO until CC and SBU OVP FETs are on and the dead battery resistors are off. 5.7 9.5 ms dVPWR_OFF/dt Minimum slew rate for CC and FETs turn off during a power off. -0.5 V/µs Overvoltage Protection tOVP_RESPONSE_CC OVP response time on the CCx pins. Time from OVP asserted until OVP FETs turn off. 70 ns tOVP_RESPONSE_SBU OVP response time on the SBUx pins. Time from OVP asserted until OVP FETs turn off. 80 ns tOVP_RECOVERY_CC OVP recovery time on the CCx pins. Once an OVP has occurred, the minimum time duration until the CC FETs turn back on. Remove OVP for CC FETs to turn back on. 0.9 2.3 ms tOVP_RECOVERY_CC_DB OVP recovery time on the CCx pins. Once an OVP has occurred, the minimum time duration until the CC FETs turn back on and the dead battery resistors turn off. Remove OVP for CC FETs to turn back on. 5 ms tOVP_RECOVERY_SBU OVP recovery time on the SBUx pins. Once an OVP has occurred, the minimum time duration until the SBU FETs turn back on. Remove OVP for SBU FETs to turn back on. 0.62 ms tOVP_FLT_ASSERTION Time from OVP Asserted to /FLT assertion. FLT assertion is 10% of the maximum value. Set C_CCx or C_SBUx above the maximum OVP threshold. Start the time where it passes the typical OVP threshold value. 20 µs tOVP_FLT_DEASSERTION Time from CC FET turn on after an OVP to FLT deassertion. 5 ms TPD4S201 SLVSIF2 – JULY 2025 www.ti.com 8 Submit Document Feedback Copyright © 2025 Texas Instruments Incorporated Product Folder Links: TPD4S201 |
