Frequently Asked Questions
What operating configurations is the BTS 775 G suitable for?
It can operate in H-Bridge configuration, or as a bridge or quad-switch by connecting its separate power transistor sources to different pins.
What safety protections are built into the output stages?
The outputs feature full short-circuit protection against ground and supply voltage shorts. Additionally, it includes overtemperature shutdown with hysteresis.
How does this device improve efficiency compared to traditional designs?
Its ultra low Resistance (R) minimizes power dissipation, achieving 'Silicon instead of heatsink' by saving costs on mechanical construction.
Are the control inputs compatible with standard microcontroller signals?
Yes, the GH1 and GH2 control inputs are TTL/CMOS compatible Schmitt-Triggers with hysteresis for reliable signal processing.
