Built-in thermal shut-down protects the chip from over temperature and short circuit. The input control is 5V logic level compatible. The open drain diagnostic output indicates open circuit (no load) and over temperature status.

FUNCTIONAL DESCRIPTION The device has a diagnostic output which indicates open circuit (no load) and over temperature conditions. The output signals are processed by internal logic. To protect the device against short circuit and over-current condition, the thermal protection turns the integrated Power MOS off at a minimum junction temperature of 140 oC. When the temperature returns to about 125 oC the switch is automatically turned on again. In short circuit conditions the protection reacts with virtually no delay, the sensor being located in the region of the die where the heat is generated. PROTECTING THE DEVICE AGAINST REVERSE BATTERY The simplest way to protect the device against a continuous reverse battery voltage (-26V) is to insert a Schottky diode between pin 1 (GND) and ground, as shown in the typical application circuit (fig. 3). The consequences of the voltage drop across this diode are as follows: - If the input is pulled to power GND, a negative voltage of -VF is seen by the device. (VIL, VIH thresholds and VSTAT are increased by VF with respect to power GND). The undervoltage shutdown level is increased by VF . If there is no need for the control unit to handle external analog signals referred to the power GND, the best approach is to connect the reference potential of the control unit to node [1] (see application circuit infig. 4), which becomes the common signal GND for the whole control board. In this way no shift of VIH, VIL and VSTAT takes place and no negative voltage appears on the INPUT pin; this solution allows the use of a standard diode, with a breakdown voltage able to handle any ISO normalized negative pulses that occours in the automotive environment. 4/8 VN30NSP TRUTH TABLE INPUT Normal Operation O pen Circuit (No Load) O ver-temperature Under-voltage L H H H X O UTPUT L H H L L DIAGNOST IC H H L L H Figure 1: Waveforms Figure 2: Over Current Test Circuit 5/8 VN30NSP Figure 3: Typical Application Circuit With A Schottky Diode For Reverse Supply Protection Figure 4: Typical Application Circuit With Separate Signal Ground 6/8 VN30NSP PowerSO-10 MECHANICAL DATA DIM.
