Smart High-Side Power Switch BTS 5434G Data Sheet V1.0, 2004-01-23 4.2.2 Reverse Polarity Protection In case of reverse polarity, the intrinsic body diode causes power dissipation. Additional power is dissipated by the integrated ground resistor. Use following formula for estimation of total power dissipation Pdiss(rev) in reverse polarity mode. The reverse current through the intrinsic body diode has to be limited by the connected load. The current through sense pins IS1 to IS4 has to be limited (please refer to maximum ratings on Page 9). The current through the ground pin (GND) is limited internally by RGND. The over-temperature protection is not active during reverse polarity. 4.2.3 Over Voltage Protection In addition to the output clamp for inductive loads as described in Section 4.1.3, there is a clamp mechanism for over voltage protection. Because of the integrated ground resistor, over voltage protection does not require external components. As shown in Figure 12, in case of supply voltages greater than Vbb(AZ), the power transistor switches on and the voltage across logic part is clamped. As a result, the internal ground potential rises to Vbb - Vbb(AZ). Due to the ESD zener diodes, the potential at pin IN1, IN2 and SEN rises almost to that potential, depending on the impedance of the connected circuitry.

Smart High-Side Power Switch BTS 5434G Data Sheet V1.0, 2004-01-23 4.3 Diagnosis For diagnosis purpose, the BTS 5434G provides an Enhanced IntelliSense signal at pins IS1 to IS4. This means in detail, the current sense signal IIS, a proportional signal to the load current (ratio kILIS = IL / IIS), is provided in ON-state as long as no failure mode occurs. In case of open load in OFF-state, the voltage VIS(fault) is fed to the diagnosis pin.

Smart High-Side Power Switch BTS 5434G Data Sheet V1.0, 2004-01-23 4.3.1 ON-State Diagnosis The standard diagnosis signal is a current sense signal proportional to the load current. The accuracy of the ratio (kILIS = IL / IIS) depends on the temperature. Please refer to following Figure 14 for details. Usually a resistor RIS is connected to the current sense pin. It is recommended to use sense resistors RIS > 500 Ω. A typical value is 4.7 kΩ.

Smart High-Side Power Switch BTS 5434G Data Sheet V1.0, 2004-01-23 For open load diagnosis in off state an external output pull-up resistor (ROL) is recommended. For calculation of the pull-up resistor, just the external leakage current Ileakage and the open load threshold voltage VOUT(OL) has to be taken into account. Ileakage defines the leakage current in the complete system e.g. caused by humidity. There is no internal leakage current from out to ground at BTS 5434G. Vbb(min) is the minimum supply voltage at which the open load diagnosis in off state must be ensured. To reduce the stand-by current of the system, an open load resistor switch (SOL) is recommended. 4.3.3 Sense Enable Function The diagnosis signals have to be switched on by a high signal at sense enable pin (SEN). See Figure 17 for details on the timing between SEN pin and diagnosis signal IIS. Please note that the diagnosis is disabled, when no signal is provided at pin SEN. Figure 17 Timing of Sense Enable Signal The SEN pin circuit is designed equal to the input pin. Please refer to Figure 5 for details. The resistors Rlim are recommended to limit the current through the sense pins IS1 to IS4 in case of reverse polarity and over voltage. Please refer to maximum ratings on Page 9. The stand-by current of the BTS 5434G is minimized, when both input pins (IN1 and IN2 or IN3 and IN4) and the according sense enable pin (SENA or SENB) are on low level.
