NOTES:
4. The operating supply current and shutdown current specifications for 5V input are the same as VIN supply current specifications, i.e., 5.6V to
28V input conditions. These should also be tested with part configured for 5V input configuration, i.e., VIN = VCC5 = PVCC = 5V.
5. This is the V
CC
current consumed when the device is active but not switching. Does not include gate drive current.
6. When the input voltage is 5.6V to 28V at VIN pin, the VCC5 pin provides a 5V output capable of 50mA (max) total from the internal LDO. When
the input voltage is 5V, VCC5 pin will be used as a 5V input, the internal LDO regulator is disabled and the VIN must be connected to the VCC5.
In both cases the PVCC pin should always be connected to VCC5 pin. (Refer to the
Pin Descriptions
sections for more details.)
7. Guaranteed by design. Not production tested.
