9.2.2.3 Driving Inductive Loads

The TIOS102(x) family is capable of magnetizing and demagnetizing large inductive loads. These devices contain internal circuitry that enables fast demagnetization when configured as either P-switch or N-switch mode.

In P-switch configuration, the load inductor L is magnetized when the OUT pin is driven high. When the PNP is turned off, there is a significant amount of negative inductive kick back at the OUT pin. This voltage is clamped internally at about -15 V.

Similarly, in N-switch configuration, the load inductor L is magnetized when the OUT pin is driven low. When the NPN is turned off, there is a significant amount of positive inductive kick back at the OUT pin. This voltage is clamped internally at about 15 V.

The equivalent protection circuits are shown in Figure 9-2 and Figure 9-3. The minimum value of the resistive load R can be calculated as:
