Functional Description
The TLE 6208-3 G is a fully protected Triple-Half-Bridge-Driver designed specifically for
automotive and industrial motion control applications. The part is based on the Siemens
power technology SPT® which allows bipolar and CMOS control circuitry in accordance
with DMOS power devices existing on the same monolithic circuitry.
In motion control up to 2 actuators (DC-Motors) can be connected to the 3 halfbridge-
outputs (cascade configuration). Operation modes forward (cw), reverse (ccw), brake
and high impedance are controlled from a standard SPI-Interface. The possibility to
control the outputs via software from a central logic, allows limiting the power dissipation.
So the standard P-DSO-14-package meets the application requirements and saves
PCB-Board-space and cost. Furthermore the build-in features like Over- and
Undervoltage-Lockout, Over-Temperature-Protection and the very low quiescent current
in stand-by mode opens a wide range of automotive- and industrial-applications.

1.5 Circuit Description
Figure 2 shows a block schematic diagram of the module. There are 3 halfbridge drivers
on the right-hand side. An HS driver and an LS driver are combined to form a halfbridge
driver in each case. The drivers communicate via the internal data bus with the logic and
the other control and monitoring functions: undervoltage (UV), overvoltage (OV),
overtemperature (TSD), charge pump and fault detect.
Two connection interfaces are provided for supply to the module: All power drivers are
connected to the supply voltage VS. These are monitored by overvoltage and
undervoltage comparators with hysteresis, so that the correct function can be checked
in the application at any time.
The logic is supplied by the VCC voltage, typ. with 5 V. The VCC voltage uses an internally
generated Power-On Reset (POR) to initialize the module at power-on. The advantage
of this system is that information stored in the logic remains intact in the event of short-
term failures in the supply voltage VS. The system can therefore continue to operate
following VS undervoltage, without having to be reprogrammed. The “undervoltage”
information is stored, and can be read out via the interface. The same logically applies
for overvoltage. “Interference spikes” on VS are therefore effectively suppressed.
The situation is different in the case of undervoltage on the VCC connection pin. If this
occurs, then the internally stored data is deleted, and the output levels are switched to
high-impedance status (tristate). The module is initialized by VCC following restart
(Power-On Reset = POR).
The 16-bit wide programming word or control word (see Table Input Data Protocol) is
read in via the DI data input, and this is synchronized with the clock input CLK. The status
word appears synchronously at the DO data output (see Table Diagnosis Data
Protocol). It is also possible to connect two TLE 6208-3 G in a daisy chain configuration.
The DO data output of one device is connected with the DI data input of the second
device. In this configuration these two devices are controlled with a single CSN chip
select and using a 32-bit wide control word.
The transmission cycle begins when the chip is selected with the CSN input (H to L). If
the CSN input changes from L to H then the word which has been read in becomes the
control word. The DO output switches to tristate status at this point, thereby releasing the
DO bus circuit for other uses.
The INH inhibit input can be used to cut off the complete module. This reduces the
current consumption to just a few µA, and results in the loss of any data stored. The
output levels are switched to tristate status. The module is reinitialized with the internally
generated POR (Power-On Reset) at restart.
This feature allows the use of this module in battery-operated applications (vehicle body
control applications).
