9.2.2.3 Driving Inductive Loads

The TIOS101(x) family is capable of magnetizing and demagnetizing inductive loads up to 1.5 H. 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 -75 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 75 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:
