On board minimum set of electrical components (as for device datasheet recommendation) is enabling the user to directly connect the load, the power supply and the microcontroller without any additional effort in external component design and connection. The VN7003ALH is a single channel high-side driver manufactured using ST proprietary VIPower® technology and housed in the Octapak package. The device is designed to drive 12 V automotive grounded loads through a 3 V and 5 V CMOS-compatible interface, providing protection and diagnostics. The device integrates advanced protective functions such as load current limitation, overload active management by power limitation and overtemperature shutdown. A combination of INPUT and FR_DIAG pins latches the output in case of fault, disables the latch-off functionality and enables OFF-state diagnostic. Figure 1.

The package includes a through-hole resistor, to be mounted on TP1-TP2 - see Figure 4. Different Rsense values can be adopted based on user preference. Another option is soldering an SMD resistor on the dedicated PCB pad, as shown in Figure 5. Figure 3. No sense resistor Figure 4.
