Question
L9362: Clamping energy specification
Hello,
I'm using smart low-side driver L9362 and I'm confused about clamping energy information presented on datasheet:
-in absolute maximum rating is declared an energy clamping limit of 50mJ with 2ms pulse width, 10ohm, 16mH
-in figure 8 is declared an energy of 200mJ with 2ms pulse width
My questions are:
1-Can you define 'pulse width'? It's referred to input or output? It's referred to level high or low?
2-Why the energy specification in absolute maximum rating doesn't coincide with figure 8 (50mJ vs 200mJ)? Figure 8 is referred to entire device capability?
3-How much is supply voltage with 10ohm and 16mH load?
4-How is possible that the device is able to clamp 200mJ with the junction already at 150°C? Which temperature reach the junction?
