3 / 5 page 3 Electrical Characteristics continued PARAMETER TEST CONDITIONS MIN TYP MAX UNIT Package Pin Description PACKAGE PIN # PIN SYMBOL FUNCTION 8L PDIP & SO 1 FLAG Indicates whether current through the IGBT has reached a pre- set level. 2 SENSE+ Positive input to current comparator. 3 SENSEÐ Ground (SENSE-) for current sense resistor. 4 Gnd Ground connection. 5 OUT Output voltage to IGBT (MOSFET) gate. 6 CLI Current limit input increase. 7 CTRL Control input. 8VCC Supply voltage. The flag indicates when the voltage across the two sense pins is approaching a current limit level that has been determined by the value of the external sense resistor (RSENSE) and the state of the CTRL and CLI pins. If the voltage across the sense pins (SENSE+, SENSE-) is less than the flag turn-on voltage, then the FLAG is off. When the voltage between the sense pins equals the FLAG turn on voltage, the FLAG will latch on until the CTRL pin goes low. FLAG is disabled whenever CTRL is low. Changing the CLI pin from low to high will increase nominal FLAG turn on voltage by approximately 45%. Table 1 FLAG Timing Sequence The CS8312 output (OUT) saturates and supplies voltage to the IGBT (or MOSFET) gate once the CTRL switches from low to high. As current through the IGBT (MOSFET) increases and the voltage across the sense resistor passes the flag turn on voltage, the FLAG will turn on. If the cur- rent through the sense resistor continues to rise and the sense resistor voltage reaches the regulation sense volt- age, then the gate voltage will fall to a level that regulates the driver and maintains the regulation sense voltage at the sense resistor. Changing the CLI pin from a logic low to a logic high increases the FLAG turn on voltage by approximately 45% and the regulation sense voltage by approximately 39% respectively.
