VINP voltage (VINP) = 24 V, MVDD voltage (VMVDD) = 3.3 V, SVDDx voltage (VSVDDx) = 3.3 V, VOUT1 voltage (VOUT1) = 24 V, VOUT2 voltage (VOUT2) = 3.3 V, and ambient temperature (TA) = 25°C for typical specifications. Minimum and maximum specifications apply over the entire operating range of 4.5 V ≤ VINP ≤ 60 V, 2.3 V ≤ VMVDD ≤ 5.5 V, 1.8 V ≤ VSVDDx ≤ 5.5 V, and −40°C ≤ TJ ≤ +125°C, unless otherwise noted.
