9.3 System Examples

9.3.1 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 17. The external components required are: a

Figure 17. TPS16630 Configured for a Simple Power Supply Path Protection

Protection features with this configuration include:

•

40 V (maximum) over voltage clamp output

•

Inrush current control with 24V/240 µs output voltage slew rate

•

Accurate current limiting with Auto-Retry

10 Power Supply Recommendations

The TPS1663x eFuse is designed for the supply voltage range of 4.5 V

located more than a few inches from the device, an input ceramic bypass capacitor higher than 0.1 μF is

recommended. Power supply must be rated higher than the current limit set to avoid voltage droops during

overcurrent and short circuit conditions.
