10.3 System Examples
10.3.1 Simple 24-V Power Supply Path Protection
With the TPS1663x, a simple 24-V power supply path protection can be realized using a minimum of three
external components, as shown in the schematic diagram in Figure 10-9. The external components required are
a R(ILIM) resistor to program the current limit and C(IN) and C(OUT) capacitors.

Protection features with this configuration include:
• 39-V (maximum) overvoltage clamp output
• Inrush current control with 24-V/500-µs output voltage slew rate
• Accurate current limiting with auto-retry
10.4 Power Supply Recommendations
The TPS1663x eFuse is designed for the supply voltage range of 4.5 V ≤ VIN ≤ 60 V. If the input supply is
located more than a few inches from the device, TI recommends an input ceramic bypass capacitor higher than
0.1 μF. Power supply must be rated higher than the current limit set to avoid voltage droops during overcurrent
and short circuit conditions.
10.4.1 Transient Protection
In case of short circuit and overload current limit, when the device interrupts current flow, input inductance
generates a positive voltage spike on the input and output inductance generates a negative voltage spike on the
output. The peak amplitude of voltage spikes (transients) depends on the value of inductance in series to the
