SPT01-335 basic application

Figure 8. PNP high side sensor configuration

Figure 9. NPN low side sensor configuration

Note:

It is advised to use diodes D1 and D3, which are the external devices in the package, as

switch overvoltage protection and power supply reverse polarity protection since they allow

better cooling design with PCB pad implementation. D2, the middle diode, can be dedicated

to the power supply overvoltage protection because it would run only in pulse mode with

basic PCB pad footprint.
