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 10 and Figure 11 for details. Nevertheless,
the maximum allowed load inductance is limited.

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). 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
pin.
In case of loss of device ground, it’s recommended to use input resistors between the microcontroller and the
BTT6010-1EKA to ensure switching OFF of the channel.
In case of loss of module or device ground, a current (IOUT(GND)) can flow out of the DMOS. Figure 14 sketches
the situation.

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.

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 in addition 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 BTT6010-1EKA remains ON. In the case the BTT6010-1EKA 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 the 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.

Reverse Polarity Protection
In case of reverse polarity, the intrinsic body diode 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 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 = RIN = RSENSE
= 10 kΩ.
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 BTT6010-1EKA 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.

Temperature Limitation in the Power DMOS
The channel incorporates both an absolute (TJ(SC)) and a dynamic (TJ(SW)) temperature sensor. 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 stage (latch behavior).

Diagnostic Functions
For diagnosis purpose, the BTT6010-1EKA provides a combination of digital and analog signals at pin IS. 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 is enabled.
7.1
IS Pin
The BTT6010-1EKA 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 20. The accuracy of the sense current depends on temperature and load
current. 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.

Figure 21 and Figure 22 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 provide across full

Figure 21 Current Sense for Nominal Load
7.3.1
SENSE Signal Variation as a Function of Temperature and Load Current
In some applications a better accuracy is required around half the nominal current IL(NOM). To achieve this accuracy
requirement, a calibration on the application is possible. To avoid multiple calibration points at different load and
temperature conditions, the BTT6010-1EKA allows limited derating of the kILIS value, at a given point (IL3; TJ =
+25 °C). This derating is described by the parameter ΔkILIS. 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 red lines indicate the kILIS accuracy without calibration.

SENSE Signal in Open Load
Open Load in ON Diagnostic
7.3.3.1
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 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
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 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 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.

Open Load Diagnostic Timing
Figure 26 shows the timing during either Open load in ON or OFF condition when the DEN pin is HIGH. Please
note that a delay tsIS(FAULT_OL_OFF) has to be respected after the falling edge of the input and rising edge of the DEN,
when applying an open load in OFF diagnosis request, otherwise the voltage VOUT cannot be guaranteed and the
diagnosis can be wrong.

SENSE Signal with OUT 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 BTT6010-1EKA, which can be recognized at the current sense

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 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 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 will indicate open load in OFF state and indicate open load in ON
state.

8.1
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 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 an
input resistor.

DEN Pin
The DEN pin enables and disables the diagnostic functionality of the device. The pin has the same structure as
the INput pin, please refer to Figure 28.
8.3
Input Pin Voltage
The IN 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.
