General description

The TLE 7230 R is an Octal Low-Side Switch in Smart Power Technology (SPT) with a Serial Periph-

eral Interface (SPI) and eight open drain DMOS output stages. It 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 in parallel for PWM applications. These

features make the TLE 7230 R particularly suitable for engine management and body systems.
