The TLE6232GP is protected by embedded protection functions and designed for automotive and industrial applications. The output stages are controlled via an SPI Interface.Additionally all six channels can be controlled direct in parallel for PWM applications. Therefore the TLE6232GP is particularly suitable for engine management and powertrain systems.
Features of the TLE6232GP are:(1)short circuit protection up to 24 V;(2)16 bit serial data input and diagnostic output (2 bit/ch. acc. SPI protocol);(3)direct parallel control of all six channels for PWM applications;(4)compatible with 3V micro controllers;(5)electrostatic discharge (ESD) protection;(6)parallel inputs high or low active programmable.The serial SPI interface makes possible communication between TLE6232 and the microcontroller.TLE6232GP always works in slave mode whereas the microcontroller provides the master function. The maximum baud rate is 5MBaud.
The absolute maximum ratings of the TLE6232GP can be summarized as:(1)continuous drain source voltage (OUT1...OUT8) Vds:45V;(2)input voltage, all inputs and data lines Vin:-0.3 to +7V;(3)supply voltage Vs:-0.3 to +7 V;(4)power dissipation (mounted on PCB) @ TA = 25°C Ptot:3.3W.In order to increase the possible number of SPI participants on one and the same CS signal,bits 7 and 6 of the instruction byte are fixed as shown above. While receiving the first two bits of the instruction byte the data output SO has to be in tri-state. After having received the first two bits TLE6232 has to decide if it is addressed (bit 7 = high, bit 6 = low). In this case the remaining 6 bits of the instruction byte and the data byte are accepted and the diagnostic feed-back respectively the data byte content (MUX, SCON) is sent to the microcontroller. Otherwise instruction and data bits are rejected and SO remains in tri-state.

TLE6236G General Description
Octal Low-Side Switch in Smart Power Technology (SPT) with a Serial Peripheral Interface (SPI) and eight open drain DMOS output stages. The TLE 6236 G is protected by embedded protection functions and designed for automotive and industrial applications. The output stages are controlled via an SPI Interface. Additionally four channels can be controlled direct in parallel for PWM applications. The open load detection (pull down sources) can be disabled via the OL/PRG pin. Then the leakage current is reduced to 1A (max.) to avoid e.g. the glowing of LEDs in off state.
Therefore the TLE 6236 G is particularly suitable for body control units, dash board illumination or engine management systems.
