3 Description

The TPS1663x is an easy to use, positive 60 V, 6 A

eFuse with a 31 mΩ integrated FET. Protection for

the load, source and eFuse itself are provided along

with

adjustable

features

such

as

overcurrent

protection, output slew rate control, overvoltage

protection and undervoltage lockout. The TPS16630

device features an adjustable over voltage cut-off

functionality whereas the TPS16632 features a fixed

a 40 V output voltage clamp. The TPS16332 device

integrates adjustable output power limiting (PLIM)

functionality that simplifies and enables compliance to

standards such as IEC61010-1. The device also

includes

adjustable

over

current

functionality.

PGOOD can be used for enable and disable control

of the downstream DC-DC converters.

A shutdown pin provides external control for enabling

and disabling the internal FET as well as placing the

device in a low current shutdown mode. For system

status monitoring and downstream load control, the

device provides fault and a precise current monitor

output. The MODE pin allows flexibility to configure

the device between the two current-limiting fault

responses (latch off and auto-retry).

The devices are available in a 4-mm × 4-mm 24-pin

VQFN as well as a 6.5-mm x 4.4-mm 20-pin

HTSSOP package and are specified over a –40°C to

+125°C temperature range.
