overview EV-VND7020AJ 2/7 docid025740 rev 4 1 overview the EV-VND7020AJ evaluation board comes pre-assembled with a vnd7020aj-e high- side driver. on board minimum set of electrical components (as for device datasheet recommendation) enables the user to directly connect the load, the power supply and the microcontroller without any additional effort in external component design and connection. the vnd7020aj-e is a double channel high-side driver manufactured using st proprietary vipower m0-7 technology and housed in powersso-16 package. it 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 with configurable latch-off. 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 the detection of overload and short circuit to ground, short to v cc 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 resistor sharing among similar devices. figure 1.
