Description This board provides you an easy way to connect STMicroelectronics® VIPower® M0-7 technology into your existing system. Table 1. Device summary Order Code Reference EV-VN7004CH VN7004CH Evaluation Board DocID029856 Rev 1 For further information contact your local STMicroelectronics sales office. 1/8 www.st.com Overview 1 EV-VN7004CH Overview The board comes pre-assembled with VN7004CH high-side driver. 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 VN7004CH 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 sense enable pin allows OFF-state diagnosis to be disabled during the module low-power mode as well as external sense resistor sharing among similar devices. 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.
