VNF1048FTR

Overview

The VNF1048FTR is a high-side switch controller designed for intelligent fuse protection in 12V, 24V, and 48V automotive applications. It operates with a single output and supports an 8 MHz switching frequency. The device functions within a temperature range of -40°C to +150°C and utilizes a QFN32L surface-mount package. Key electrical parameters include a maximum operating supply voltage of 48V, a typical operating supply current of 8mA, and an output current capability of 250µA. The component features rise and fall times of 60µs and 2.3µs respectively, and holds AEC-Q100 qualification.

Feature Summary

Intelligent eFuse protection replacing traditional fuses in automotive power distribution
SPI interface for host control, diagnostics, and configurable protection settings
Integrated ADC for monitoring junction temperature, NTC input, output voltage, and MOSFET drain-source voltage
Robust fail-safe mechanisms including battery undervoltage shutdown and external MOSFET desaturation detection

Applications

Automotive power distribution systems
Smart high-side switch implementations for 12V, 24V, and 48V architectures
Intelligent high-current fuse replacement solutions

Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when sourcing. Confirm AEC-Q100 qualification status aligns with project requirements. Ensure the QFN32L package dimensions match the PCB footprint design. Check humidity sensitivity levels for proper storage and reflow soldering profiles during assembly.

Selection Notes

Select this controller for applications requiring precise digital current sensing via an external shunt resistor. It is suitable for designs needing low standby current and comprehensive diagnostic feedback through SPI. Consider the external MOSFET compatibility and gate drive requirements when integrating into the high-side configuration.

Part Context

This component belongs to the STi2Fuse series from STMicroelectronics, specialized for automotive environments. It serves as a bridge between microcontrollers and power stages, offering advanced protection features typically found in dedicated eFuse ICs but with the flexibility of a controller architecture.
