(1) The current sense in the ADC will not accurately read below the current VREV5V0/RPP5V or VREVHV/RPPHV due to the reverse blocking behavior. When reverse blocking is disabled, the values given for accuracy are valid.

(2) Limit the resistance from the HV_GATE1/2 pins to the external FET gate pins to < 1Ω to provide adequate response time to short circuit events.

(3) Maximum capacitance on VBUS when configured as a source must not exceed 12 µF.

(4) Specified for a 10-mΩ RSENSE resistor and 10-mΩ RSENSE application code setting. Values will scale with a different RSENSE resistance and application code setting.

(5) Settings selected automatically by application code for the current limit needed in the application.
