TPS2595x
SLVSE79A – JUNE 2017 – REVISED AUGUST 2017
TPS2595x, 2.7V-18V, 4-A, 34-mΩ eFuse With Overvoltage Protection
1 Features
•1 Wide Input Voltage Range: 2.7 V to 18 V
– 20-V Absolute Maximum
– 3 V to 18 V for TPS2595x5 version
• Low On-Resistance: R_ON = 34 mΩ (typical)
• Overvoltage Protection Clamp (3.8-, 5.7-, and
13.7-V options)
• Adjustable Undervoltage Lockout (UVLO)
• Adjustable Current Limit with Monitor Output (ILM)
– Current Range: 0.5 A to 4 A
– Current Accuracy: ±10% (≥2 A)
• Fast Short Circuit Protection
• Adjustable Output Slew Rate Control (dVdt)
• Over Temperature Protection (OTP)
• Fault Indication Pin (FLT )
• UL 2367 Recognition (Pending)
• Safe During Single Point Failure Test (UL60950)
2 Applications
• Hot-Swap, Hot-Plug
• SSDs and HDDs
• Industrial Systems
• White Goods
• Set-Top Box
• Digital TV
Current limit level can be set with a single external
resistor. Overvoltage events are limited by internal
clamping circuits to a safe fixed maximum, with no
external components required.
Applications with particular inrush current
requirements can set the output slew rate with a
single external capacitor.
Quick output discharge function can be implemented
in the TPS2595x5 by connecting OUT to FLT pin.
The TPS2595x family is available in multiple package
options for various applications. The devices are
characterized for operation over the temperature
range of –40°C to +125°C.

3 Description
The TPS2595x family of eFuses (An Integrated FET
Hotswap device) is a highly integrated circuit
protection and power management solution in a small
package. The devices use few external components
and provide multiple protection modes. They are a
robust defense against overloads, short circuits,
voltage surges, and excessive inrush current.
