7.3.2.5 Multi-level digital input (VDSLVL)

The VDS monitor threshold level of DRV816x is configurable using VDSLVL pin. The pin can set 8 levels, LEVEL0 to LEVEL7, with an external resistor connected between VDSLVL and GND. The 7 threshold levels are determined by Table 7-5. As shown in Figure 7-13, if one digital pulse is applied to VDSLVL pin, additional 6 threshold levels are available. If VDSLVL pin is open, VDS monitor function is disabled. The VDS monitor threshold infomration is latched at the device power up.
