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 VCC 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 “Pin Descriptions” on page 10 for more details). 7. Limits established by characterization and are not production tested. 8. It is recommended to use VCC5 as the pull-up source. Electrical Specifications Operating Conditions: VIN = 12V, PVCC shorted with VCC5, TA = +25°C; Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established by characterization and are not production tested. (Continued) PARAMETER SYMBOL TEST CONDITIONS MIN TYP MAX UNITS Typical Performance Curves FIGURE 1.
