Inductive Load
5.3.1
Output Clamping
When switching OFF inductive loads with high side switches, the voltage VOUT drops below ground potential,
because the inductance intends to continue driving the current. 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 9 and Figure 10 for details. Nevertheless,
the maximum allowed load inductance is limited.

Inverse Current Capability
4
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 12). 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). If the 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. 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 functions are
available.

Protection Functions

Protection Functions
The device provides integrated protection functions. 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
BTS5200-4EKA to ensure switching OFF of channels.
In case of loss of module or device ground, a current (IOUT(GND)) can flow out of the DMOS. Figure 13 sketches
the situation.
ZGND is recommended to be a diode in parallel to a resistor (1 kΩ).

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 14 sketches the undervoltage mechanism.

Overvoltage Protection
VS(OP)
VS
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 15
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 INx, DSELx, 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 BTS5200-4EKA remains ON. In the case the BTS5200-4EKA 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. ZGND with a resistor (27 Ω) in series to
the diode will offer better results.

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 16 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 = 4.7 kΩ. ZGND is recommended to be a 1 kΩ resistor in parallel to a diode.
During reverse polarity, no protection functions are available.

Overload Protection
In case of overload, such as high inrush of cold lamp filament, or short circuit to ground, the BTS5200-4EKA 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 17 shows the behavior of
the current limitation as a function of the drain to source voltage.

current limitation _200m.vsd
Each channel incorporates an absolute (TJ(SC)) temperature sensor and a switch OFF timer that is started by an
overcurrent event. The activation of these protection mechanisms will cause an overheated channel to switch OFF
to prevent destruction. A temperature limitation switch OFF latches the output until the temperature has reached
an acceptable value. Figure 18 gives a sketch of the situation.
A retry strategy is implemented such that when the DMOS temperature has cooled down enough, the switch is
switched ON again, if the IN pin signal is still high (restart behavior).

6.5.3
Short Circuit Appearance with Channels in Parallel
The four channels are not synchronised in the restart event. When the channels are in temperature limitation, the
channel which has cooled down the fastest doesn’t wait for the other to be cooled down as well to restart. Thus,
it is not recommended to use the device with channels in parallel.

Diagnostic Functions
For diagnosis purpose, the BTS5200-4EKA provides a combination of digital and analog signals at pin IS. In case
the diagnostic is disabled via DEN, pin IS becomes high impedance. In case DEN is activated, the sense current

IS Pin
The BTS5200-4EKA provides a sense signal called 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 19. The accuracy of the sense current depends on temperature and load
current. The sense pin multiplexes the currents IIS(0), IIS(1), IIS(2) and IIS(3) via the pins DSEL0 and DSEL1. Thanks
to this multiplexing, the matching between kILISCHANNEL0, kILISCHANNEL1, kILISCHANNEL2 and kILISCHANNEL3 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.

SENSE Signal in the Nominal Current Range
Figure 20 and Figure 21 show the current sense as a function of the load current in the power DMOS. Usually, a
pull-down resistor RIS is connected to the current sense IS pin. This resistor has to be higher than 560 Ω to limit
the power losses in the sense circuitry. A typical value is 1.2 kΩ. The blue curve represents the ideal sense
current, assuming an ideal kILIS factor value. The red curves shows the accuracy the device provides across full
temperature range at a defined current.

SENSE Signal Variation as a Function of Temperature and Load Current
In some applications a better accuracy is required at smaller currents. To achieve this accuracy requirement, a
calibration on the application is possible. To avoid multiple calibration points at different load and temperature
conditions, the BTS5200-4EKA allows limited derating of the kILIS value, at a given point (IL3; TJ = +25 °C). This
derating is described by the parameter ∆kILIS. Figure 21 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 red lines indicate the kILIS accuracy without calibration.

SENSE Signal in Open Load
7.3.3.1
Open Load in ON Diagnostic
If the channel is ON, a leakage current can still flow through an open load, for example due to humidity. 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 23 shows the SENSE current behavior in this area. The red curve shows a typical product curve. The blue
curve shows the ideal current sense.

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 24 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.

SENSE Signal in Short Circuit to VS
In case of a short circuit between the OUTput-pin and the VS pin, all or portion (depending on the short circuit
impedance) of the load current will flow through the short circuit. As a result, a lower current compared to the
normal operation will flow through the DMOS of the BTS5200-4EKA, which can be recognized at the current 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. Figure 26 gives a sketch of the situation.

SENSE Signal in Case of Overload
An overload condition is defined by a current flowing out of the DMOS reaching the current limitation and / or the
absolute dynamic temperature swing TJ(SW) is reached, and / or the junction temperature reaches the thermal
shutdown temperature TJ(SC). 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 an thermal restart behavior, such that when the overtemperature or the exceed dynamic
temperature condition has disappeared, the DMOS is reactivated if the IN is still at logical level one. If the DEN
pin is activated, and DSEL pin is selected to the correct channel, the IS pin is not toggling with the restart
mechanism and remains to IIS(FAULT).
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 and
indicate open load in ON state. The unaffected channels indicate normal behavior as long as the IINV current is not
exceeding the maximum value specified in Chapter 5.4.

Input Circuitry
The input circuitry is compatible with 3.3 and 5 V microcontrollers. 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 27 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 an
input resistor.

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.
