9.2.4 Application Curves
All the waveforms below are captured on an evaluation setup with six (6) TPS25984 eFuses in parallel. All the pullup supplies are derived from a separate standby rail.
Figure 9-6 Input Hot Plug: VIN Stepped Up from 0 V to 12 V, CLOAD = 50 mF, CDVDT = 33 nF, and RILIM on Each Device = 442 Ω
Figure 9-8 Power Up into Short: VIN = 12 V, EN/UVLO Stepped Up From 0 V to 3 V, RIREF = 40.2 kΩ, RILIM on Each Device = 442 Ω, and OUT Shorted to GND
Figure 9-10 Circuit-Breaker Response: VIN = 12 V, CITIMER = 22 nF, CLOAD = 50 mF, RIMON = 200 Ω, RIREF = 40.2 kΩ, and Load Current Stepped up From 250 A to 400 A for > 20 ms
Figure 9-12 Two Devices in Parallel Temperature Rise with 110-A DC Current at Room Temperature (No Air-Flow)
Figure 9-7 Start-up with EN/UVLO: VIN = 12 V, EN/UVLO Stepped Up From 0 V to 3 V, CLOAD = 50 mF, RLOAD(Start-up) = 0.48 Ω, CDVDT = 33 nF, and RILIM on Each Device = 442 Ω
Figure 9-9 Transient Overload: VIN = 12 V, CITIMER = 22 nF, CLOAD = 50 mF, RIMON = 200 Ω, RIREF = 40.2 kΩ, and Load Current Stepped from 250 A to 300 A then 250 A within 10 ms
Figure 9-11 Output Hot-Short Response: VIN = 12 V, RIMON = 200 Ω, RIREF = 40.2 kΩ, and OUT Shorted to GND
