Trip Point Tolerance Selection
The 3.3VTOL and 5VTOL inputs allow independent
selection of the reset trip points. If 5VTOL is connected to
the 5V supply input, a 10% tolerance is selected. If
5VTOL is grounded, a 5% tolerance is selected.
If 3.3VTOL is connected to the 3.3V supply input, a 20%
tolerance is selected. If 3.3VTOL is grounded, a 10%
tolerance is selected. (Refer to table below.) The
3.3VTOL and 5VTOL tolerance select inputs should be
tied to the ground or to the respective input supply
voltage pin, 3.3VIN or 5VIN.
