3 Description

The TPS16530 is an easy to use, positive 58-V,

4.5-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 and undervoltage lockout.

PGOOD can be used for enable and disable control

of the downstream DC-DC converters.

The enable pin provides external control for enabling

and disabling the internal FET. The shutdown pin

can be used for putting the device in low power

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 20-pin HTSSOP

and 24-pin VQFN packages and are specified over a

–40°C to +125°C temperature range.
