TPS259470LRPW

The TPS25947xx family of eFuses is a highly
integrated circuit protection and power management
solution in a small package. The devices provide
multiple protection modes using very few external
components and are a robust defense against
overloads, short-circuits, voltage surges, reverse
polarity and excessive inrush current. With integrated
back-to-back FETs, reverse current flow from output
to input is blocked at all times, making the devices
well suited for power MUX/ORing applications as
well as systems which need load side energy hold
up storage in case input power supply fails. The
devices use linear ORing based scheme to ensure
almost zero DC reverse current and emulate ideal
diode behavior with minimum forward voltage drop
and power dissipation.
Output slew rate and inrush current can be adjusted
using a single external capacitor. Loads are protected
from input overvoltage conditions either by clamping
the output to a safe fixed maximum voltage (pin
selectable), or by cutting off the output if input
exceeds an adjustable overvoltage threshold. The
devices respond to output overload by actively limiting
the current or breaking the circuit. The output current
limit threshold as well as the transient overcurrent
blanking timer are user adjustable. The current limit
control pin also functions as an analog load current
monitor.
The devices are available in a 2-mm × 2-mm,
10-pin HotRod QFN package for improved thermal
performance and reduced system footprint.
The devices are characterized for operation over a
junction temperature range of –40°C to +125°C.
