Description
The BTF6070-2EKV is a 60 mΩ dual channel Smart High-Side Power Switch, embedded in a PG-DSO-14-40 EP,
Exposed Pad package, providing protective functions and diagnosis. The power transistor is built by an
N-channel vertical power MOSFET with charge pump. The device is integrated in Smart6 HV technology. It is
specially designed to drive Valve Applications in the harsh automotive environment. For lighting applications the
nominal bulb load of P10W+P5W 24 V or P10W 12 V is considered.

SENSE Signal in the Nominal Current Range
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 1.8 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.

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 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 BTF6070-2EKV allows limited derating of the kILIS value, at a given point (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 red lines indicate the derating on the parameter across temperature and voltage, assuming one calibration
point at nominal temperature and nominal battery voltage.
The black 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 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 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.

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, when applying an open load in
OFF diagnosis request, otherwise the diagnosis can be wrong.

SENSE Signal with OUT in Short Circuit to VS
t
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 BTF6070-2EKV, 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 27 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 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 IS(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 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 Pins
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 10 kΩ input resistor.

DEN Pin
Input cir cuitry.emf
The DEN pin enable and disable the diagnostic functionality of the device. The pins have the same structure as
the INput pins, 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.
