Overview
The TPS14P50 and TPS05P50 are 5-A e-fuse switches with voltage clamp and current limit protection functions integrated. The TPS14P50 integrates a 15-V over-voltage clamp and the TPS05P50 integrates a 6.1-V over-voltage clamp. The over-voltage clamp function can limit the output voltage during the input voltage surge to protect the load from damage. The TPS14P50 and TPS05P50 integrate an adjustable current limit function. The current limit level can be set from 2 A to 5 A by connecting an external resistor at the ILIM pin and the current limit accuracy is ±15% typically.
To limit the inrush current and meet the output voltage smoothly ramp up requirement, the TPS14P50 and TPS05P50 integrate a soft-start function, which can be adjusted by a capacitor connected at the dVdt pin.
Both of the TPS14P50 and the TPS05P50 products are guaranteed to operate in the ambient temperature range from −40°C to +125°C. Additionally, both products provide the thermal-enhanced DFN3X3-10 package to enable sustained operation despite significant dissipation across the device.
