Description

STM1068 device monitors supply voltage VCC and the state of EN and INH inputs. Depending on logical combination of these inputs, the output OUT is connected to VIN or GND and the pass gate between PKX and POX is either enabled or disabled (see Table 2 and Table 3 for more details).

The device offers several voltage thresholds, VTH+ (see Table 9) and it is available in miniature flip chip 8-bump package.
