58-V 4.5-A eFuse with pulse current support

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.
