CS8312
CS8312 is IGBT manufactured by onsemi.
IGBT Ignition Predriver with Dynamic Current Regulation
The CS8312 is a bipolar microprocessor interface IC designed to drive an IGBT (or logic level MOSFETs) powering large inductive loads in harsh operating environments. The IC’s dynamic current limit function lets the microprocessor adjust the current limit threshold to the real time needs of the system.
CLI, the current limit input, sets the current limit for the IGBT high or low as directed by the system microprocessor. CLI also raises and lowers the threshold on the diagnostic FLAG output signal. The FLAG output signals the microprocessor when the current level approaches current limit on the IGBT. The CTRL input enables the FLAG function.
