RESET = HIGH indicates that high side MOSFET is allowed to be turned on.
RESET = LOW indicates that high side MOSFET is OFF.
IN = LOW indicates that high side MOSFET is on.
IN = HIGH indicates that high side MOSFET is off.
RechFET = ON indicates that the recharge MOSFET is on.
RechFET = OFF indicates that the recharge MOSFET is off.
1 Note: Refer to the RESET functionality graph of Figure 7, for VCC and VBS voltage ranges under which
the functionality is normal.
