10 Power Supply Recommendations

There are no power sequence requirements for the LSF family. Table 10-1 provides recommended operating voltages for all supply and input pins.

Table 10-1 Recommended Operating Voltages
PARAMETERMINTYPMAXUNIT
Vref_A(1)reference voltage (A)0.655.5V
Vref_Breference voltage (B)Vref_A + 0.85.5V
