9.2.2.3 Driving Inductive Loads

The TIOL111(x) family is capable of magnetizing and demagnetizing inductive loads up to 1.5H. 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 CQ output is driven high. When the PNP is turned off, there is a significant amount of negative inductive kick back at the CQ pin. This voltage is clamped internally at about -75 V.

Similarly in N-switch configuration, the load inductor L is magnetized when the CQ output is driven low. When the NPN is turned off, there is a significant amount of positive inductive kick back at the CQ pin. This voltage is clamped internally at about 75 V.

The equivalent protection circuits are shown in Figure 18 and Figure 19. The minimum value of the resistive load R can be calculated as:
