19 / 37 page ![]() DocID025589 Rev 3 19/37 L7987 Functional description 37 Figure 9. Current limit and programming resistor The minimum programmed current limit can't be lower than ISKIP = 0.5 A (typical), also in case of foldback detection. 4.6 Overtemperature protection It is recommended that the device never exceeds the maximum allowable junction temperature. This temperature increase is mainly caused by the total power dissipated from the integrated Power MOSFET. To avoid any damage to the device when reaching high temperature, the L7987 device implements a thermal shutdown feature: when the junction temperature reaches 170 °C (typ.) the device turns off the Power MOSFET and shuts down. When the junction temperature drops to 155 °C (typ.), the device restarts with a new soft- start sequence. |
