CS8312
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.
