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 accurate

overcurrent protection, fast short circuit protection,

output slew rate control, overvoltage protection

and undervoltage lockout. The TPS16332 device

integrates adjustable output power limiting (PLIM)

functionality that simplifies and enables compliance

to standards such as IEC61010-1 and UL1310.

The device also includes adjustable overcurrent

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 package and are specified over a –40°C to

+125°C temperature range.
