Notes:

6. Logic operation for V_Sof -5V to +50V.

7. Provided V_Bdoesn’t exceed absolute maximum rating of 60V.

8. For operation of V_CC= 4.7V to 4.9V, an external bootstrap Schottky diode (0.3V Vfd, 1A) is necessary, see Figure 4. For operation V_CC≥ 4.9V, the

external Schottky diode is not required.
