AS3715 − Detailed Description – Power Management Functions

Figure 46:

NTC ß Influence

NTC ß Influence Diagram: Shows the voltage drop on the NTC over temperature for different ß using

RNTC=10kΩ, Rp=15kΩ and INTC=150uA.

The chip is supporting up to 4 temperature levels for

supervision.

Figure 47:

NTC Supervision

NTC Supervision: Example threshold voltages for different temperatures and ß using RNTC=10kΩ, Rp=15kΩ and

INTC=150uA.

The base values (T1min, T2min, T3min and T4min) for the

comparator levels are marked in the table above. To adjust the

comparator levels to the needed temperature levels dedicated

adjust bits can be set (32-64 7mV steps).
