Figure 8 shows the dependencies in terms of temperature and supply voltage for the typical ON-state resistance. The behavior in reverse polarity is described in Chapter 6.4. Figure 8 Typical ON-state Resistance A high signal (see Chapter 8) at the input pin causes the power DMOS to switch ON with a dedicated slope, which is optimized in terms of EMC emission. 5.2 Turn ON/OFF Characteristics with Resistive Load Figure 9 shows the typical timing when switching a resistive load.

To prevent the destruction of the device by avalanche due to high voltages, there is a voltage clamp mechanism ZDS(AZ) implemented that limits negative output voltage to a certain level (VS - VDS(AZ)). Please refer to Figure 10 and Figure 11 for details. Nevertheless, the maximum allowed load inductance is limited.

This energy can be calculated with following equation: E = V DS L RL ------ AZ V S – V DS AZ -------------------------------RL R L IL ln 1 – -------------------------------- + I L VS – VDS AZ Following equation simplifies under the assumption of RL = 0 2 1 E = --- L I 2 (1) . VS 1 – -------------------------------VS – VDS AZ (2) The energy, which is converted into heat, is limited by the thermal design of the component. See Figure 12 for the maximum allowed energy dissipation as a function of the load current. Figure 12 Maximum Energy Dissipation Single Pulse, TJ(0) = 150 °C; VS = 28V 5.4 Inverse Current Capability In case of inverse current, meaning a voltage VINV at the OUTput higher than the supply voltage VS, a current IINV will flow from output to VS pin via the body diode of the power transistor (please refer to Figure 13). The output stage follows the state of the IN pin, except if the IN pin goes from OFF to ON during inverse. In that particular case, the output stage is kept OFF until the inverse current disappears. Nevertheless, the current IINV should not be higher than IL(INV). Otherwise, the second channel can be corrupted and erratic behavior can be observed. If the affected channel is OFF, the diagnostic will detect an open load at OFF. If the affected channel is ON, the diagnostic will detect open load at ON (the overtemperature signal is inhibited). At the appearance of VINV, a parasitic diagnostic can be observed at the unaffected channel. After, the diagnosis is valid and reflects the output state. At VINV vanishing, the diagnosis is valid and reflects the output state. During inverse current, no protection function are available.

These functions are designed to prevent the destruction of the IC from fault conditions described in the data sheet. Fault conditions are considered as “outside” normal operating range. Protection functions are designed for neither continuous nor repetitive operation. 6.1 Loss of Ground Protection In case of loss of the module ground and the load remains connected to ground, the device protects itself by automatically turning OFF (when it was previously ON) or remains OFF, regardless of the voltage applied on IN pins. In case of loss of device ground, it’s recommended to use input resistors between the microcontroller and the BTT6030-2EKA to ensure switching OFF of the channels. In case of loss of module or device ground, a current (IOUT(GND)) can flow out of the DMOS. Figure 14 sketches the situation. ZGND is recommended to be a resistor in serias to a diode. >-7%> :7 >(%> -7 67)27) :&%8 >(7%> (7)0 6(7)0 ()2 6()2 -2 6-2 -398+2( 03+-' -2 6-2 398 >()7( +2( 6-7 >+2( 0SWWSJKVSYRHTVSXIGXMSRWZK Figure 14 Loss of Ground Protection with External Components 6.2 Undervoltage Protection Between VS(UV) and VS(OP), the undervoltage mechanism is triggered. VS(OP) represents the minimum voltage where the switching ON and OFF can takes place. VS(UV) represents the minimum voltage the switch can hold ON. If the supply voltage is below the undervoltage mechanism VS(UV), the device is OFF (turns OFF). As soon as the supply voltage is above the undervoltage mechanism VS(OP), then the device can be switched ON. When the switch is ON, protection functions are operational. Nevertheless, the diagnosis is not guaranteed until VS is in the VNOM range. Figure 15 sketches the undervoltage mechanism. Data Sheet PROFET™+ 24V 21 Rev. 1.1, 2015-03-04 BTT6030-2EKA Protection Functions Figure 15 Undervoltage Behavior 6.3 Overvoltage Protection There is an integrated clamp mechanism for overvoltage protection (ZD(AZ)). To guarantee this mechanism operates properly in the application, the current in the Zener diode has to be limited by a ground resistor. Figure 16 shows a typical application to withstand overvoltage issues. In case of supply voltage higher than VS(AZ), the power transistor switches ON and the voltage across the logic section is clamped. As a result, the internal ground potential rises to VS - VS(AZ). Due to the ESD Zener diodes, the potential at pin IN and DEN rises almost to that potential, depending on the impedance of the connected circuitry. In the case the device was ON, prior to overvoltage, the BTT6030-2EKA remains ON. In the case the BTT6030-2EKA was OFF, prior to overvoltage, the power transistor can be activated. In the case the supply voltage is in above VBAT(SC) and below VDS(AZ), the output transistor is still operational and follows the input. If at least one channel is in the ON state, parameters are no longer guaranteed and lifetime is reduced compared to the nominal supply voltage range. This especially impacts the short circuit robustness, as well as the maximum energy EAS capability. 73: -7%> 7 (%> (7%> &%8 7)27) (7)0 ()2 -2 -2 )7( -7 +2( 3ZIVZSPXEKITVSXIGXMSRWZK Figure 16 Overvoltage Protection with External Components Data Sheet PROFET™+ 24V 22 Rev. 1.1, 2015-03-04 BTT6030-2EKA Protection Functions 6.4 Reverse Polarity Protection In case of reverse polarity, the intrinsic body diodes of the power DMOS causes power dissipation. The current in this intrinsic body diode is limited by the load itself. Additionally, the current into the ground path and the logic pins has to be limited to the maximum current described in Chapter 4.1 with an external resistor. Figure 17 shows a typical application. RGND resistor is used to limit the current in the Zener protection of the device. Resistors RDSEL, RDEN, and RIN are used to limit the current in the logic of the device and in the ESD protection stage. RSENSE is used to limit the current in the sense transistor which behaves as a diode. The recommended value for RDEN = RDSEL = RIN = RSENSE = 10 k . ZGND is recommended to be a resistor in series to a diode. During reverse polarity, no protection functions are available. Figure 17 Reverse Polarity Protection with External Components 6.5 Overload Protection In case of overload, such as high inrush of cold lamp filament, or short circuit to ground, the BTT6030-2EKA offers several protection mechanisms. 6.5.1 Current Limitation At first step, the instantaneous power in the switch is maintained at a safe value by limiting the current to the maximum current allowed in the switch IL(SC). During this time, the DMOS temperature is increasing, which affects the current flowing in the DMOS. The current limitation value is VDS dependent. Figure 18 shows the behavior of the current limitation as a function of the drain to source voltage.

Activation of either sensor will cause an overheated channel to switch OFF to prevent destruction. Any protective switch OFF latches the output until the temperature has reached an acceptable value. Figure 19 gives a sketch of the situation. No retry strategy is implemented such that when the DMOS temperature has cooled down enough, the switch is switched ON again. Only the IN pin signal toggling can re-activate the power strage. (latch behavior).

These signals are called SENSE. In case the diagnostic is disabled via DEN, pin IS becomes high impedance. In case DEN is activated, the sense current of the channel X is enabled/disabled via associated pin DSEL. Table 7 gives the truth table. Table 7 Diagnostic Truth Table DEN DSEL 0 don’t care Z 1 0 Sense output 0 IIS(0) 1 1 Sense output 1 IIS(1) 7.1 IS IS Pin The BTT6030-2EKA provides a SENSE current written IIS at pin IS. As long as no “hard” failure mode occurs (short circuit to GND / current limitation / overtemperature / excessive dynamic temperature increase or open load at OFF) a proportional signal to the load current (ratio kILIS = IL / IIS) is provided. The complete IS pin and diagnostic mechanism is described on Figure 20. The accuracy of the SENSE depends on temperature and load current. The IS pin multiplexes the current IIS(0) and IIS(1), via the pin DSEL. Thanks to this multiplexing, the matching between kILISCHANNEL0 and kILISCHANNEL1 is optimized. Due to the ESD protection, in connection to VS, it is not recommended to share the IS pin with other devices if these devices are using another battery feed. The consequence is that the unsupplied device would be fed via the IS pin of the supplied device.

Usually, a pull-down resistor RIS is connected to the IS pin. This resistor has to be higher than 560 to limit the power losses in the sense circuitry. A typical value is 1.2 k . The blue curve represents the ideal SENSE, assuming an ideal kILIS factor value.

To achieve this accuracy requirement, a calibration on the application is possible. To avoid multiple calibration points at different load and temperature conditions, the BTT6030-2EKA allows limited derating of the kILIS value, at nominal load current (IL3; TJ = +25 °C). This derating is described by the parameter kILIS. Figure 22 shows the behavior of the SENSE current, assuming one calibration point at nominal load at +25 °C. The blue line indicates the ideal kILIS ratio. The green lines indicate the derating on the parameter across temperature and voltage, assuming one calibration point at nominal temperature and nominal battery voltage.

The parameter IL(OL) gives the threshold of recognition for this leakage current. If the current IL flowing out the power DMOS is below this value, the device recognizes a failure, if the DEN (and DSEL) is selected. In that case, the SENSE current is below IIS(OL). Otherwise, the minimum SENSE current is given above parameter IIS(OL). Figure 24 shows the SENSE current behavior in this area. The red curve shows a typical product curve. The blue curve shows the ideal kILIS ratio. Figure 24 Current Sense Ratio for Low Currents 7.3.3.2 Open Load in OFF Diagnostic For open load diagnosis in OFF-state, an external output pull-up resistor (ROL) is recommended. For the calculation of pull-up resistor value, the leakage currents and the open load threshold voltage VOL(OFF) have to be taken into account. Figure 25 gives a sketch of the situation. Ileakage defines the leakage current in the complete system, including IL(OFF) (see Chapter 5.5) and external leakages, e.g, due to humidity, corrosion, etc.... in the application. To reduce the stand-by current of the system, an open load resistor switch SOL is recommended. If the channel x is OFF, the output is no longer pulled down by the load and VOUT voltage rises to nearly VS. This is recognized by the device as an open load. The voltage threshold is given by VOL(OFF). In that case, the SENSE signal is switched to the IIS(FAULT). An additional RPD resistor can be used to pull VOUT to 0V. Otherwise, the OUT pin is floating. This resistor can be used as well for short circuit to battery detection, see Chapter 7.3.4.

As a result, a lower current compared to the normal operation will flow through the DMOS of the BTT6030-2EKA, which can be recognized at the SENSE signal. The open load at OFF detection circuitry can also be used to distinguish a short circuit to VS. In that case, an external resistor to ground RSC_VS is required.

Please refer to Chapter 6.5 for details. In that case, the SENSE signal given is by IIS(FAULT) when the diagnostic is selected. The device has a thermal latch behavior, such that when the overtemperature or the exceed dynamic temperature condition has disappeared, the DMOS is reactivated only when the IN is toggled LOW to HIGH. If the DEN pin is activated, and DSEL pin is selected to the correct channel, the SENSE follows the output stage. If no reset of the latch occurs, the device remains in the latching phase and IIS(FAULT) at the IS pin, eventhough the DMOS is OFF. 7.3.6 SENSE Signal in Case of Inverse Current In the case of inverse current, the sense signal of the affected channel will indicate open load in OFF state during OFF state and indicate open load in ON during ON state. The unaffected channel indicates normal behavior as long as the IINV current is not exceeding the maximum value specified in Chapter 5.4.

The concept of the input pin is to react to voltage thresholds. An implemented Schmitt trigger avoids any undefined state if the voltage on the input pin is slowly increasing or decreasing. The output is either OFF or ON but cannot be in a linear or undefined state. The input circuitry is compatible with PWM applications. Figure 28 shows the electrical equivalent input circuitry. In case the pin is not needed, it must be left opened, or must be connected to device ground (and not module ground) via a 4.7k input resistor. Figure 28 Input Pin Circuitry 8.2 DEN / DSEL Pin The DEN / DSEL pins enable and disable the diagnostic functionality of the device. The pins have the same structure to INput pins, please refer to Figure 28. 8.3 Input Pin Voltage The IN, DSEL and DEN use a comparator with hysteresis. The switching ON / OFF takes place in a defined region, set by the thresholds VIN(L) Max. and VIN(H) Min. The exact value where the ON and OFF take place are unknown and depends on the process, as well as the temperature. To avoid cross talk and parasitic turn ON and OFF, a hysteresis is implemented. This ensures a certain immunity to noise.
