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.

TLE 6208-3 G 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.

TLE 6208-3 G Every driver block from DRV 1 to 3 contains a low-side driver and a high-side driver. Both drivers are connected internally to form a half-bridge at the output. This reduction of output pins was necessary to meet the small P-DSO-14 package. When commutating inductive loads, the dissipated power peak can be significantly reduced by activating the transistor located parallel to the internal freewheeling diode.
