Product Overview
VNF1048FTR is a high-side switch controller with intelligent fuse protection for 12V, 24V and 48V automotive applications. It is an advanced controller for a power MOSFET in high side configuration, designed for the implementation of an Intelligent high side switch for 12V, 24V and 48V automotive applications. The control IC is interfaced to a host microcontroller through a 3.3V and 5V CMOS-compatible SPI interface and provides protection and diagnostics to the system. High precision uni-directional digital current sense via SPI through an external high side shunt resistor. It features protection features such as battery undervoltage shut-down, external MOSFET desaturation shutdown configurable via SPI, hard short circuit latch-off configurable via SPI, current vs time latch-off configurable via SPI (fuse-emulation), device overtemperature shutdown and external MOSFET overtemperature shutdown. It has operating voltage range (extended) of 6V to 70V and standby current (max) of 70µA.
- AEC-Q100 automotive qualified
- 32bit ST-SPI interface compatible with 3.3V and 5V CMOS level
- 2 stage charge pump, gate drive for an external MOSFET in high side configuration
- Input for a NTC resistor to monitor the external MOSFET temperature
- Very low standby current, robust fail-safe functionality through internal and external controls
- SPI register lock-out by dedicate digital input pin, integrated ADC for TJ/VNTC/VOUT/VDS conversion
- Intelligent high current fuse replacement for automotive applications
- Especially intended for automotive power distribution applications
- Maximum transient supply voltage of 70V, operating voltage range from 6V to 60V
- SPI I/O supply voltage of 3V to 5.5V, SPI standby current (max) of 5µA
