To prevent the destruction of the device due to high voltages, there is a voltage clamp mechanism implemented that keeps the negative output voltage at a certain level (VS-VDS(AZ)). Please refers to Figure 6 and Figure 7 for details. Nevertheless, the maximum allowed load inductance is limited.

Data Sheet 13 Rev.1.0, 2008-04-29 BTS4175SGA Protection Mechanisms 6 Protection Mechanisms The device provides embedded protective functions. Integrated protection 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, where 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 pin. In that case, a maximum I(OUTGND) can flow out of the output. 6.2 Undervoltage Protection Below VSOP_min, the under voltage mechanism is met. If the supply voltage is below the under voltage mechanism, the device is OFF (turns OFF). As soon as the supply voltage is above the under voltage mechanism, then the device can be switched ON and the protection functions are operational. 6.3 Overvoltage Protection There is a clamp mechanism for over voltage protection. To guarantee this mechanism operates properly in the application, the current in the zener diode ZDAZ has to be limited by a ground resistor. Figure 9 shows a typical application to withstand overvoltage issues. In case of supply greater than VS(AZ), the power transistor switches ON and the voltage across 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 rises almost to that potential, depending on the impedance of the connected circuitry. Integrated resistors are provided at the IN pin to protect the input circuitry from excessive current flow during this condition. VS VBAT IN R ST ZD AZ R IN LOGIC ST OUT ZD ESD GND R GND Overvoltage protection single with diag.vsd Figure 9 Data Sheet Over voltage protection with external components 14 Rev.1.0, 2008-04-29 BTS4175SGA Protection Mechanisms In the case the supply voltage is in between of VS(SC) max and VDS(AZ), the output transistor is still operational and follow the input. If the channel is in ON state, parameters are no longer warranted and lifetime is reduced compared to normal mode. This specially impacts the short circuit robustness, as well as the maximum energy EAS the device can handle. 6.4 Reverse Polarity Protection In case of reverse polarity, the intrinsic body diode 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 logical pins has to be limited to the maximum current described in Chapter 4.1, sometimes with an external resistor. Figure 10 shows a typical application. The RGND resistor is used to limit the current in the zener protection of the device. Resistors RIN and RST is used to limit the current in the logic of the device and in the ESD protection stage. The recommended value for RGND is 150Ω, for RST 0/1= 15kΩ. In case the over voltage is not considered in the application, RGND can be replaced by a Shottky diode.

Current limitation At first step, the instantaneous power in the switch is maintained to a safe level by limiting the current to the maximum current allowed in the switch IL(LIM). During this time, the DMOS temperature is increasing, which affects the current flowing in the DMOS. Thermal protection At thermal shutdown, the device turns OFF and cools down. A restart mechanism is used, after cooling down, the device restarts and limits the current to IL(SCR). Figure 11 shows the behavior of the current limitation as a function of time.

Figure 12 shows the equivalent circuitry. As long as no “hard” failure mode occurs (Short circuit to GND / Over temperature or open load in OFF), the signal is permanently high, and due to a required external pull-up to the logic voltage will exhibit a logic high in the application.

For calculation of the pull-up resistor value, the leakage currents and the open load threshold voltage VOL(OFF) has to be taken into account. Figure 13 gives a sketch of the situation and Figure 14 shows the typical timing diagram. Ileakage defines the leakage current in the complete system, including IL(OFF) (see Chapter 5.4) 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. Data Sheet 18 Rev.1.0, 2008-04-29 BTS4175SGA Diagnostic Mechanism If the channel 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 open load. The voltage threshold is given by VOL(OFF). In that case, the ST signal is switched to a logical low VSTL.

The concept of the Input pin is to react to voltage transition and not to voltage threshold. With the Schmidt trigger, it is impossible to have the device in an un-defined state, if the voltage on the input pin is slowly increasing or decreasing. The output is either OFF or ON but cannot be in an linear or undefined state. The input circuitry is compatible with PWM applications. Figure 16 shows the electrical equivalent input circuitry. The pull down current source ensures the channel is OFF with a floating input.
