See the switching time waveform VIH is internally clamped at around 6V. This pin can be connected to a higher voltage through an external resistor that does not exceed a calculated value of 10 mA at the input pin. Note 1: The rated current is the current of Tc=85 oC when the battery voltage is 13V, resulting in a voltage drop of 0.5 V Note 2: IOL (off) = (VCC-vol)/rol (see picture) Note 3: T1 (on) : Active state output T1 (off): Deactivate state output T2 (off): Minimum ON time after thermal shutdown for deactivating state output TPOVL TPOL: ISO definition (see figure).

Functional Description: The device has a diagnostic output indicating open load conditions in off and on states, output short to VCC and over temperature. Truth tables show input, diagnostic and output voltage levels under normal operating and fault conditions. The output signal is processed by internal logic. The open load diagnostic output has 5 ms filtering. The filter provides a continuous signal for the fault condition after an initial delay of about 5 ms. This means that during normal operation, a disconnection lasting less than 5 ms will not affect the status output. Likewise, any reconnection less than 5 ms during the disconnection duration will not affect the status output. In overtemperature conditions, the state goes low without delay. Starting from the falling edge of the input signal, the state output is initially low in a fault condition (over temperature or open load) and will return with a delay (tpovl) under an over temperature condition and a return delay (tpol) under an open load. These features are fully compliant with International Standards Office (ISO) requirements for high-side drivers in cars. To protect the device from short circuits and overcurrent, thermal protection shuts down the integrated power MOS at a minimum junction temperature of 140 oC. When the temperature returns to 125 oC, the switch automatically turns on again. In the event of a short circuit, there is little delay in the protective response, and the sensor is located in the area of the mold where heat is generated. Drive inductive loads, the device's internal function ensures fast demagnetization

Typical voltage (Vdemag) is -18V. This feature allows a substantial reduction in power dissipation according to the following formula: pdem=0.5 lload(iload)2[(vcc+vdemag)/vdemag], where f=switching frequency, vdemag=demagnetization voltage Based on this formula, the inductance and/or value of current to avoid thermal shutdown. In a given thermal environment, the maximum inductance that causes the die temperature to reach the shutdown temperature is a function of fixed VCC, VDEMAG, and F load current.
Protection against load unloading according to ISO T/R 7637/1 - Test Pulse 5 The device is capable of withstanding Class II Test Pulse 5 (vs=46.5V) without any external components. This means that all functions of the device perform as designed after exposure to secondary disturbances. VN06SP can withstand three-level test pulse 5, add an external resistor of 150 ohms between the ground terminal and the ground terminal, and add a 1000μF filter capacitor between the VCC terminal and the ground terminal (if rload≤20Ω).
To protect the device from reverse battery, the easiest way to protect the device from continuous reverse battery voltage (-26V) is to insert a Schottky diode between ground and ground, as in the typical application circuit. The result of the voltage drop across this diode is as follows: If the input is pulled to power ground, the device will see a negative voltage -vf. (VIL, VIH threshold, and VSTAT are increased by VF with respect to power ground). The undervoltage shutdown level is increased by VF. If the control unit does not need to handle the external analog signal of the reference power GND, the best way is to connect the reference potential of the control unit to the node [6] which becomes the common signal GND of the whole control board Avoidi. NG shift of VIH, VIL and VSTAT. This solution allows the use of standard diodes
