Note:

1. Effect of INV on VOUT (TOL = x and OVSH = 0), ENx and VINx refer to the corresponding output.

Notes:

1. Effect of INV on Vout (TOL= x and OVSH=1). ENx/ENy refers to EN1 and EN3 or EN2 and EN4, respectively. VINx/VINy refers to VIN1 and VIN3 or VIN2

and VIN4, respectively. Note: Vout3/Vout4 are not used in this mode.

2. Having all four enables low is an invalid state for the device operation. This state will not cause any harm to the device or system, but operation may not be as expected.

with the under-voltage monitor by VIN1 or VIN2, respectively, as shown in Figure 8 and Figure 9.

Note: Refer to the section, "Thresholds/Over-Voltage Setting/Tolerance" for information regarding the adjustable threshold.
