Remarks:
Default status of input pins:
To assure a defined status of the logic input pins in case of disconnection, these pins are
internally secured by pull up / pull down current sources with approx. 20µA. The high voltage
proof input INH should be secured by an external pull down resistor close to the device. The
following table shows the default status of the logic input pins.
Input pin
PWM and DIR
DT/DIS (active high)
Definition:
In this datasheet a duty cycle of 98% means that the GLx pin is 2% of the PWM period in
high condition.
Remark: Please consider the influence of the dead time and the propagation time differ-
ences for the input duty cycle
Functional description
Description of Dead Time Pin / Disable Pin / Reset
This pin allows to adjust the internal generated dead time. The dead time protects the exter-
nal high side and lowside Mosfets in the same halfbridge against a lowohmic connection be-
tween battery and GND and the resulting cross current through these Mosfets. The adjust-
able dead time allows to minimize the power dissipation caused by the current flowing
through the body diode during switching the halfbridge.
In addition this pin allows to reset the diagnosis registers without shut down of any output
stage as well as the possibility to shut down all outputs simultaneously.
Condition of DT/DIS pin
0 - 3.5V
> 4V
Description of Inhibit functionality
In automotive applications which are permanently connected to the battery line, it is very im-
portant to reduce the current consumption of the single devices. Therefore the TLE6281G
offers an inhibit mode to put the device to sleep and assure low quiescent currents. To deac-
tivate the inhibit mode the INH pin has to be set to high. This can be done by connecting this
pin to voltages between 3.3 and 60V without external protection. An inhibit mode means a
complete reinitialisation of the device.
Description of Diagnosis
The two ERx pins are open collector outputs and have to be pulled up with external pull up
resistors to 5V. In normal conditions both ERx signals are high. In case of shutdown of any

Function
Adjust dead time between 10ns and 3.1µs
a) Reset of diagnosis register if DT/DIS voltage is higher than
4V for a time between 3.1µs and 3.6µs
b) Shut down of output stages if DT/DIS voltage is higher
than 4V for a time above 7µs (Active pull down of gate volt-
age)
