Description EV-VN7000AY board provides you an easy way to connect STMicroelectronics® VIPower® M0-7 technology into your existing system.

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 VN7000AY is a single channel high-side driver manufactured using ST proprietary VIPower® M0-7 technology and housed in PowerSSO-36 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 and overload management by ΔTJ and over-temperature shut-down with latch-off. A toggling on the INPUT pin unlatches the output in case of fault. A dedicated multifunction multiplexed analog output pin delivers sophisticated diagnostic functions including high precision proportional load current sense, supply voltage feedback and chip temperature sense, in addition to the detection of overload and short circuit to ground, short to VCC and OFF-state open-load. A sense enable pin allows OFF-state diagnosis to be disabled during the module lowpower mode as well as external sense resistor sharing among similar devices. A R_mode pin allows to switch low respectively high RDSon operating mode, so to adapt current sense precision and current limitation accordingly to the selected load. Figure 1.

It controls OUT0 switch state. 14..18 N/A Not connected In case the user wishes to utilize the Current Sense / MultiSense function of the device, it is necessary to plug a sense resistor in Rsense. 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. DB3565 - Rev 2 page 3/10 EV-VN7000AY Board Connection Figure 3. No sense resistor Figure 4.
