Electrical Specifications
Recommended operating conditions unless otherwise noted. Refer to Block Diagram and Typical Application
Schematic. V IN = 5.6V to 24V, or VCC_5V = 5V ±10%, C_VCC_5V = 4.7μF, T A = -40°C to +85°C (Note 5),
Typical values are at T A = +25°C, unless otherwise specified. (Continued)

NOTES:
2. In normal operation, where the device is supplied with voltage on the V IN pin, the VCC_5V pin provides a 5V output capable of 60mA (min).
When the VCC_5V pin is used as a 5V supply input, the internal LDO regulator is disabled and the V IN input pin must be connected to the
VCC_5V pin. (Refer to the Pin Descriptions section for more details.)
3. This is the total shutdown current with V IN = 5.6 and 24V.
4. Operating current is the supply current consumed when the device is active but not switching. It does not include gate drive current.
5. Limits established by characterization and are not production tested.
6. Check Note 2 for VCC_5V and VIN configurations at 5V ±10% input applications. ISL9440, ISL9440A’s PGOOD signal will fall LOW when VIN
pin voltage drops below 5.55V (TYP), which results from the early warning detection on VIN pin voltage. ISL9441 doesn’t have an early warning
function, so when VIN pin voltage is below 5.55V, PGOOD will not be pulled LOW; ISL9441’s PGOOD only shows the output voltage regulation
status.
