3. In normal operation, where the device is supplied with voltage on the V
4. This is the total shutdown current with V
5. Operating current is the supply current consumed when the device is active but not switching. It does not include gate drive current.
6. Limits should be considered typical and are not production tested.
7. Established by characterization. The full scale current of 32µA is recommended for optimum current sample and hold operation. See “Feedback
When the VCC_5V pin is used as a 5V supply input, the internal LDO regulator is disabled and the V
VCC_5V pin. (Refer to “Pin Descriptions” on page 10 for more details.)
