3 Description

The TPS2660x devices are compact, feature rich high

voltage eFuses with a full suite of protection features.

The wide supply input range of 4.2 to 60 V allows

control of many popular DC bus voltages. The device

can withstand and protect the loads from positive and

negative supply voltages up to ±60 V. Integrated back

to back FETs provide reverse current blocking feature

making the device suitable for systems with output

voltage holdup requirements during power fail and

brownout conditions. Load, source and device

protection are provided with many adjustable features

including overcurrent, output slew rate and

overvoltage, undervoltage thresholds. The internal

robust protection control blocks along with the high

voltage rating of the TPS2660x helps to simplify the

system designs for Surge protection.

A shutdown pin provides external control for enabling

and disabling the internal FETs 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 precise current monitor

output. The MODE pin allows flexibility to configure

the device between the three current-limiting fault

responses (circuit breaker, latch off, and Auto-retry

modes).

The devices are available in a 5-mm × 4.4-mm 16-pin

HTSSOP as well as 5-mm x 4-mm 24-pin VQFN

package and are specified over a –40°C to +125°C

temperature range.
