Figure 7.10 Junction Temperature dependency of over current detection 7.7. Over temperature protection.
The over temperature protection prevents destruction due to the temperature rise of this product and MOSFET, so if junction temperature exceeds Thermal detection temperature, normal off driver operates and turns the external FET off. When junction temperature drops below hysteresis set temperature, this product returns to normal operation. is es VIN yster H TOT TOT - Thys Tj VGATE VDIAG ● VIN: IN pin input voltage ● VGATE: GATE pin output voltage ● VDIAG: DIAG pin output voltage ● TOT: Over heat detection temperature ● Thys: Hysteresis of thermal detection
