IGBT Ignition Predriver

with Dynamic Current Regulation

Features

Description

The CS8312 is a bipolar micropro-

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 diag-

nostic FLAG output signal. The

FLAG output signals the micropro-

cessor when the current level

approaches current limit on the

IGBT. The CTRL input enables the

FLAG function.

■ µP Compatible Inputs

cessor interface IC designed to

drive an IGBT (or logic level

MOSFETs) powering large induc-

tive loads in harsh operating envi-

ronments. The ICÕs dynamic cur-

rent limit function lets the micro-

processor adjust the current limit

threshold to the real time needs of

the system.

■ Adjustable Current Limit

Thresholds

■ External Sense Resistor
