Functional Description The device has a diagnostic output indicating open circuit (no load) and above temperature conditions. The output signal is processed by internal logic.
To protect the device from short circuit and overcurrent state, the thermal protection shuts down the integrated power mos junction temperature of 140oc. When the temperature returns to about 125 degrees, the c switch is automatically turned on again.
In the event of a short circuit, the protective device reacts with almost no delay, and the sensor is located in the area of the mold where heat is generated. Protect the device from reverse battery Protect the device from battery continuous reverse voltage (-26V) to GND by inserting a Schottky diode between pin 1 (GND) and ground, as shown in the Typical Application Circuit (Figure 3). The consequences of a voltage drop on this diode are as follows: if the input is pulled to supply GND, the device can see a voltage of -vf. (Vil, Vih village vf increase threshold and vstat on power ground). The undervoltage shutdown level increases VF.
If the control unit does not need to handle the external analog signal GND referring to the power supply, the best way is to connect the control unit to the reference potential of the node [1], which becomes the common signal GND for the entire control board.
This way, VIH, VIL, and VSTAT are placed unchanged and no negative voltages appear at the input pins; this solution allows the use of standard diodes with a breakdown voltage capable of handling any ISO-standardized negative-pulse automotive environment occours.
