2.7-V to 24-V, 2.7-mΩ, 15-A eFuse with hot-swap protection, ±1.5% current monitor & adj. fault mgmt.

The TPS25982 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 and excessive inrush

current.

Overvoltage events are limited by

internal cutoff circuits, with multiple device options to select the overvoltage

threshold.

Multiple device options exist to

select between the response to overcurrent conditions, circuit breaker or active

current limiter. The overcurrent limit and fast-trip (short-circuit) threshold can

be set with one 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 TPS25982 devices are available in

a small 4mm × 4mm QFN package. The devices are characterized for operation over a

junction temperature range from –15°C to 125°C.
