TPS2521

SLVSFX8 – MARCH 2021

TPS2521xx, 2.7 - 5.7 V, 4 A, 31-mΩ True Reverse Current Blocking eFuse with Input

Reverse Polarity Protection

blocked at all times, making the device well suited for

systems which need load side energy hold up storage

1 Features

•

Wide operating input voltage range: 2.7 V to 5.7 V

28-V absolute maximum

Withstands negative voltages up to – 15 V

Integrated back-to-back FETs with low On-

Resistance: R_ON= 31 mΩ (typ)

Ideal diode operation with true reverse current

blocking

Fast overvoltage clamp (OVC) with pin-selectable

threshold (3.8 V, 5.7 V) with 5-μs (typ) response

time

Overcurrent protection with load current monitor

output (ILM)

– Active current limit response

– Adjustable threshold (I_LIM) 0.5 A - 4.44 A

in case input power supply fails.

Output current limit level can be set with a single

external resistor. It is also possible to get an accurate

sense of the output load current by measuring the

voltage drop across the current limit resistor.

•

Applications

with

particular

inrush

current

requirements can set the output slew rate with a

single external capacitor. Loads are protected from

input overvoltage conditions by clamping the output to

a safe fixed maximum voltage (pin selectable).

•

The devices are available in a 2-mm × 2-mm,

10-pin HotRod QFN package for improved thermal

performance and reduced system footprint.

•

±10% accuracy for I_LIM> 1 A

The devices are characterized for operation over a

junction temperature range of –40°C to +125°C.

– Adjustable transient blanking timer (ITIMER) to

allow peak currents up to 2 x I_LIM

– Output load current monitor accuracy: ±6%

(I_OUT≥ 1 A)

3 Description

The TPS2521x family of eFuses is a highly integrated

circuit protection and power management solution

in a small package. The devices provide multiple

protection modes using very few external components

and are

robust defense against overloads,

short-circuits, voltage surges, reverse polarity and

excessive inrush current. With integrated back-to-

back FETs, reverse current flow from output to input is
