Thermal stress test results
1.
All channels shorted: fSWITCH = 0.5 Hz, VCC = 28V, duration 72 hours, TA = 25°C.
2.
All channels shorted: fSWITCH = 0.5 Hz, VCC = 28V, duration 8 hours, TA = 85°C.
3.
All channels shorted: fSWITCH = 0.5 Hz, VCC = 28V, duration 8 hours, TA = –25°C.
Test Results: The case temperature with 8 channels shorted oscillates between 116 and
119°C with an ambient temperature of 25°C. The case temperature increases to between 116
and 121°C with an ambient temperature of 85°C.

Figure 34. Switching with short circuit: VCC =
24V, f = 0.5Hz, Wave2 = VSTATUSOPT,
Wave1 = VINOPT, Wave4 = ICH1OUT
