1. What types of thermal sensors are used in PMICs?
Commonly, PMICs incorporate thermistors, diodes, and other temperature-sensing elements to monitor heat and protect the system from thermal damage.
-
2. What happens if a PMIC overheats?
Overheating can lead to efficiency losses, performance degradation, or even permanent damage to the PMIC or surrounding components.
-
3. Can PMICs control fan speeds for thermal management?
Yes, some PMICs include fan control circuits that adjust fan speed based on temperature readings to maintain optimal thermal conditions.
-
4. How does power density impact thermal management in PMICs?
Higher power densities generate more heat, requiring more robust thermal solutions to avoid performance issues.
