Description

The ACPL-332J is an advanced 2.5 A output current,

easy-to-use, intelligent gate driver which makes IGBT

fault protection compact, aordable, and easy-to

implement. Features such as integrated V

detection,

under voltage lockout (UVLO), “soft” IGBT turn-o, isolated

open collector fault feedback and active Miller clamping

provide maximum design exibility and circuit protec-

tion.

The ACPL-332J contains a GaAsP LED. The LED is optically

coupled to an integrated circuit with a power output

stage. ACPL-332J is ideally suited for driving power IGBTs

and MOSFETs used in motor control inverter applications.

The voltage and current supplied by these optocouplers

make them ideally suited for directly driving IGBTs with

ratings up to 1200 V and 150 A. For IGBTs with higher

ratings, the ACPL-332J can be used to drive a discrete

power stage which drives the IGBT gate. The ACPL-332J

has an insulation voltage of V

Application Information Product Overview Description The ACPL-332J is a highly integrated power control device that incorporates all the necessary components for a complete, isolated IGBT / MOSFET gate drive circuit with fault protection and feedback into one SO-16 package. Active Miller clamp function eliminates the need of negative gate drive in most application and allows the use of simple bootstrap supply for high side driver.

Output Control Slow IGBT Gate Discharge during Fault Condition The outputs (VOUT and FAULT) of the ACPL-332J are controlled by the combination of IF, UVLO and a detected IGBT Desat condition. Once UVLO is not active (VCC2 - VE > VUVLO), VOUT is allowed to go high, and the DESAT (pin 14) detection feature of the ACPL-332J will be the primary source of IGBT protection. UVLO is needed to ensure DESAT is functional. Once VUVLO+ > 10.5 V, DESAT will remain functional until VUVLO- < 11.1 V.
PAGE 22
Under Voltage Lockout The ACPL-332J Under Voltage Lockout (UVLO) feature is designed to prevent the application of insufficient gate voltage to the IGBT by forcing the ACPL-332J output low during power-up. IGBTs typically require gate voltages of 15 V to achieve their rated VCE(ON) voltage. At gate voltages below 13 V typically, the VCE(ON) voltage increases dramatically, especially at higher currents. At very low gate voltages (below 10 V), the IGBT may operate in the linear region and quickly overheat.
PAGE 23
Pull-up Resistor on FAULT Pin The FAULT pin is an open collector output and therefore requires a pull-up resistor to provide a high-level signal. Also the FAULT output can be wire ‘OR’ed together with other types of protection (e.g. over-temperature, overvoltage, over-current ) to alert the microcontroller.
