overview EV-VND7004AY 2/8 docid029896 rev 1 1 overview the board comes pre-assembled with vnd7004ay high-side driver. on board, a minimum set of electrical components (as for device da tasheet 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 vnd7004ay is a double channel high-side driver manufactured using st proprietary vipower technology and housed in powersso-36 packages. the device is designed to drive 12 v automotive grounded loads through a 3 v and 5 v cmos-compatible interface, and to provide protection and diagnostics. the device integrates also adv anced protective functions such as load current limitation, overload active management by power limitation and overtemperature shutdown. a faultrst pin unlatches the output in case of fault or disables the latch-off functionality. 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 t he 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 low-power mode as well as external sense resi stor sharing among similar devices. figure 1.
