General description Six Channel Low-Side Switch in Smart Power Technology (SPT) with a Serial Peripheral Interface (SPI) and six open drain DMOS output stages. The TLE 6232 GP 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 TLE 6232 GP is particularly suitable for engine management and powertrain systems.
