Functional Pin Description
Totem Pole output of Phase A comparator. This output is low when the
voltage on PA_HS_S (Source of High Side FET) is less than 50% of V
Power ground for charge pump
Logic signal input must be high (ANDed with EN2) to enable any gate drive
output.
Logic signal input must be high (ANDed with EN1) to enable any gate drive
output
Reset input
Do not connect these pins
Charge pump output
Charge pump supply
Supply voltage to the load. This pin is to be connected to the common
Drains of the external High Side FETs
Totem Pole output of Phase B comparator. This output is low when the
voltage on PB_HS_S (Source of High Side FET) is less than 50% of V
Totem Pole output of Phase C comparator. This output is low when the
voltage on PC_HS_S (Source of High Side FET) is less than 50% of V
