Description
Avago’s ACPL-337J gate drive optocoupler features fast
propagation delay with excellent timing skew perfor-
mance. Smart features that are integrated to protect
the IGBT include IGBT desaturation detection with soft-
shutdown protection and fault feedback, undervoltage
lockout and feedback, and active Miller current clamping.
This full-featured and easy-to-implement IGBT gate drive
optocoupler comes in a compact, surface-mountable
SO-16 package for space-savings. It is suitable for driving
IGBTs and power MOSFETs used in motor control and
inverter applications.
Avago isolation products provide reinforced insulation
and reliability that delivers safe signal isolation critical in
high voltage and noisy industrial applications.

Notes:
1. Derate linearly above 70 °C free-air temperature at a rate of 0.3 mA/°C.
2. Maximum pulse width = 10 µs
3. This supply is optional and is required only when negative gate drive is implemented.
4. Derate linearly above 95 °C free-air temperature at a rate of 20 mW/°C.
5. Derate linearly above 95 °C free-air temperature at a rate of 5 mW/°C. The maximum LED junction temperature should not exceed 125 °C.

Notes:
1. In most applications VCC1 will be powered up first (before VCC2) and powered down last (after VCC2). This is desirable for maintaining control of the
IGBT gate. In applications where VCC2 is powered up first, it is important to ensure that input remains low until VCC1 reaches the proper operating
voltage (minimum 4.5 V) to avoid any momentary instability at the output during VCC1 ramp-up or ramp-down.
2. 15 V is the recommended minimum operating positive supply voltage (VCC2 - VE) to ensure adequate margin in excess of the maximum VUVLO+
threshold of 13.7 V.
3. This supply is optional and is required only when negative gate drive is implemented.
