3 Description
The TPS25983 family of eFuses is a highly integrated
circuit protection and power management solution in
a small package. The devices are operational over
a wide input voltage range. A single part caters
to low-voltage systems needing minimal I*R voltage
drop as well as higher voltage, high current systems
needing low power dissipation. They are a robust
defense against overloads, short-circuits, voltage
surges, reverse current, and excessive inrush current.
Overvoltage events are limited by internal cutoff
circuits with user adjustable overvoltage threshold.
Multiple device options exist to choose between the
response to overcurrent conditions, circuit breaker, or
active current limiter. The overcurrent limit threshold
can be set with a single external resistor. The devices
intelligently manage the overcurrent response by
distinguishing between transient events and actual
faults, thereby allowing the system to function
uninterrupted during line and load transients without
compromising on the robustness of the protection
against faults. The device can be configured to
stay latched-off or retry automatically after a fault
shutdown. The number of auto-retries as well as
the retry delay are configurable with capacitors. This
enables remote systems to automatically recover from
temporary faults while ensuring that power supplies
are not stressed indefinitely due to a persistent fault.
The devices provide an option to drive an external
N-FET connected in series to facilitate reverse current
blocking in disabled or OFF state.
Also, the devices integrate an accurate analog
load current monitor to provide enhanced system
monitoring and diagnostic capabilities.
The TPS25983 devices are available in a small, 4 mm
× 4 mm QFN package. The devices are characterized
for operation over a junction temperature range of
–40°C to 125°C.
