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 1µA (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 en-

gine management systems.
