The TPS25983 family of eFuses is a highly-integrated circuit protection and power management device 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. The TPS25983 family is 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 feature enables remote systems to automatically recover from temporary faults while making sure that the 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.
