Hi,
What is the current consumption of V15 Pin in S32K322 100 Pin HDQFP?
How does the VRC_Ctrl pin regulate V15?
How to calculate the Ballast transistor current consumption? can we use the SOT 23 Package for the transistor?
@S32K322
- What is the current consumption of V15 Pin in S32K322 100 Pin HDQFP?
It is defined in the device’s datasheet Table 17 onwards.
- How does the VRC_Ctrl pin regulate V15?
The following information is provided as generic linear regulator functionality.
To maintain a constant output voltage, the linear regulator adjusts the pass device resistance by comparing the internal voltage reference to the sampled output voltage and then driving the error to zero.
- How to calculate the Ballast transistor current consumption? Can we use the SOT 23 Package for the transistor?
Refer to section 2.7.1.1 (Selecting the NPN external ballast transistor) of the Hardware Design Guidelines for S32K3 Microcontrollers.
