TLE 6208-3 G

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.

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

. 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

voltage, typ. with 5 V. The

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

. The system can therefore continue to operate

following

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

are therefore effectively suppressed.

The situation is different in the case of undervoltage on the

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

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).
