EV-VNF1248F

EV-VNF1248F is a VNF1248F evaluation board which simplifies the integration of a high-side switch controller with intelligent fuse protection into your prototype circuitry (MAX current allowed 32A, limitation due to connector used). This pre-assembled board includes VNF1248F and the essential electrical components. This setup allows for direct connections to the load, power supply and microcontroller, eliminating the need for additional external component design and connections. The VNF1248F is a high-side switch controller with intelligent fuse protection for 12V, 24V and 48V automotive applications. The control IC is interfaced with a host microcontroller through a 3.3V and 5V CMOS-compatible SPI interface and provides protection and diagnostics to the system.

• 32-bit ST-SPI interface compatible with 3.3V and 5V CMOS level
• SPI interface for host control and 2-stage charge pump
• Gate drive for an external MOSFET in high-side configuration
• Precision uni-directional digital current sense via SPI through an external high side shunt resistor
• Input for an NTC resistor to monitor the external MOSFET temperature
• Very low standby current
• Emergency stop and limp-home pins for advanced safety features
• Device configuration lock out by a dedicated digital input pin
• Integrated ADC for TJ, VNTC, VOUT, VDS and VSENSE conversion
• Protections: battery undervoltage shut-down, device overtemperature shutdown
