Built-in thermal shut-down protects the chip from over temperature and short circuit. The open drain diagnostic output indicates: open load in off state and in on state, output shorted to VCC and overtemperature. Fast demagnetization of inductive loads is achieved by negative (-18V) load voltage at turn-off. t e l o s b O Table 2. Order Codes Package Tube Tape and Reel PENTAWATT Vert. VN31 - PENTAWATT Hor.

This function allows to greatly reduce the power dissipation according to the formula: Pdem = 0.5 • Lload • (Iload)2 • [(VCC+Vdemag)/ Vdemag] • f where f = switching frequency and Vdemag = demagnetization voltage Based on this formula it is possible to know the value of inductance and/or current to avoid a thermal shut-down. The maximum inductance which causes the chip temperature to reach the shut down temperature in a specific thermal environment, is infact a function of the load current for a fixed VCC, Vdemag and f. ) s ( ct u d o FUNCTIONAL DESCRIPTION The device has a diagnostic output which indicates open load conditions in off state as well as in on state, output shorted to VCC and overtemperature. The truth table shows input, diagnostic and output voltage level in normal operation and in fault conditions. The output signals are processed by internal logic. The open load diagnostic output has a 5 ms filtering. The filter gives a continuous signal for the fault condition after an initial delay of about 5 ms. This means that a disconnection during normal operation, with a duration of less than 5 ms does not affect the status output. Equally, any reconnection of less than 5 ms during a disconnection duration does not affect the status output. No delay occur for the status to go low in case of overtemperature conditions. From the falling edge of the input signal the status output initially low in fault condition (over temperature or open load) will go back with a delay (tpovl)in case of overtemperature condition and a delay (tpol) in case of open load. These feature fully comply with International Standard Office (I.S.O.) requirement for automotive High Side Driver. To protect the device against short circuit and over current conditions, the thermal protection turns the integrated Power MOS off at a minimum junction temperature of 140 °C. When the temperature returns to 125 °C the switch is automatically turned on again. In short circuit the protection reacts with virtually no delay, the sensor being located in the region of the die where the heat is generated. Driving inductive loads, an internal function of the ) (s t c u d o r P e t e l o s b O 6/13 PROTECTING THE DEVICE AGAIST LOAD DUMP - TEST PULSE 5 The device is able to withstand the test pulse No. 5 at level II (Vs = 46.5V) according to the ISO T/R 7637/1 without any external component. This means that all functions of the device are performed as designed after exposure to disturbance at level II. The VN31 is able to withstand the test pulse No.5 at level III adding an external resistor of 150 ohm between pin 1 and ground plus a filter capacitor of 1000 µF between pin 3 and ground (if RLOAD ≤ 20 Ω). r P e t e l o s b O 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 (Figure 10). 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 in Figure 11), which becomes the common signal GND for the whole control board avoiding shift of VIH, VIL and VSTAT. This solution allows the use of a standard diode. VN31 Table 9.
