Smart Multichannel Low Side Switch with Parallel Control and SPI Interface

Block Diagram

Diagnosis

The device provides diagnosis of the load, including open load, short to GND as well as short circuit to VBatt

detection and over-load/ over-temperature indication. The SPI diagnosis flags indicates if latched fault

conditions may have occurred.

Protection

Each output stage is protected against short circuit. In case of over load, the affected channel is switched off.

The switching off reaction time is dependent on two switching thresholds. Restart of the channel is done by

clearing the Diagnosis Register 1). This feature protects the device against uncontrolled repetitive short

circuits.

There is a temperature sensor available for each channel to protect the device in case of over temperature. In

case of over temperature the affected channel is switched off and the Over-Temperature Flag is set. Restart of

the channel is done by deleting the Flag. This feature protects the device against uncontrolled temperature

toggling.

Parallel Connection of Channels

The device is featured with a central clamping structure, so-called CLAMPsafe. This feature ensures a balanced

clamping between the channels and allows in case of parallel connection of channels a high efficient usage of

the channel capabilities. This parallel mode is additionally featured by best possible parameter- and thermal

matching of the channels and by controlling the channels accordingly.
