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.
