TPS25981

SLVSGG6B – APRIL 2022 – REVISED JUNE 2023

TPS25981x 2.7 V – 16 V, 10-A, 6-mΩ eFuse with Transient Overcurrent Blanking Timer

1 Features

3 Description

•

Wide operating input voltage range: 2.7 V to 16 V

– 20-V absolute maximum

Integrated FET with low on-resistance: R_ON= 6

mΩ (typ.)

Fast overvoltage protection

– Adjustable overvoltage lockout (OVLO) with

1.2-μs (typ.) response time

The TPS25981xx 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 a robust defense against

overloads, short circuits, voltage surges and

excessive inrush current.

•

Overcurrent protection with load current monitor

output (ILM)

– Circuit-breaker response

Output slew rate and inrush current can be

adjusted using a single external capacitor. Loads

are protected from input overvoltage conditions by

cutting off the output if input exceeds an adjustable

overvoltage threshold. The devices respond to output

overload by actively limiting the current (during start-

up) or breaking the circuit (during steady-state).

The overcurrent protection threshold as well as

the transient overcurrent blanking timer are user-

adjustable. The current limit control pin also functions

as an analog load current monitor.

– Adjustable threshold (I_LIM) 1.5 A – 11 A

•

±10% accuracy for I_LIM> 5 A

– Adjustable transient blanking timer (ITIMER) to

allow peak currents up to 2 × I_LIM

– Output load current monitor accuracy: ±10%

(I_OUT≥ 3 A)

Fast-trip response for short-circuit protection

– 640-ns (typ.) response time

•

– Adjustable (2 × I_LIM) and fixed thresholds

Active high enable input with adjustable

undervoltage lockout threshold (UVLO)

Active low enable input with adjustable

undervoltage lockout threshold (OVLO)

Adjustable output slew rate control (dVdt)

Option to drive external FET for reverse current

blocking in disabled/OFF state

Overtemperature protection

Quick Output Discharge

Digital outputs

– Power Good (PG) and fault indication (FLT)

UL 2367 recognition (pending)

The devices are available in a 2-mm × 2-mm, 10-

pin HotRod^™QFN package for improved thermal

performance and reduced system footprint.

•

The devices are characterized for operation over a

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