Comparator power-on reset

The TSC20x's comparator integrates a power-on reset, allowing it to have a defined output state.

The TSC20x comparator has an open drain output, so while the VCC power supply is lower than 1.5 V, the output

is ever equal to VCC. When VCC is above 1.5 V (typ.), the output is in a low state if the COMPIN voltage is lower

than 0.6 V, as described by Figure 48, or a high state if the COMPIN voltage is higher than 0.6 V as described by

Figure 49.
