2.5 Amp Gate Drive Optocoupler with Active Miller Clamp,
Rail-to-Rail Output and UVLO in Stretched SO8
User’s Guide
Product Description
The ACPL-H342/K342 is a 2.5A output current gate drive
optocoupler with features like active Miller clamp, rail-to-
rail output and anti-cross conduction timing that helps to
simplify IGBT gate drive design without compromising on
efficiency and reliability.
ACPL-H342/K342 is ideally suited for driving IGBTs and
power MOSFETs used in motor control and renewable
energy inverter applications. The voltage and current
supplied by these optocouplers make them suitable for
direct driving of IGBTs with ratings up to 1200 V and 150 A.
ACPL-K342 has an insulation voltage of V
IORM
= 1140 V
PEAK
.
It is also immune to common-mode voltage transients as
high as 1.5 kV and as fast as 40 kV/
Ps.
Applications
x Isolated IGBT/MOSFET Gate Drive
x AC and Brushless DC Motor Drives
x Industrial Inverters
x Renewable Energy Inverters
x Uninterruptible Power Supplies (UPS)
About Evaluation Board
The ACPL-H342/K342 evaluation board allows a power-
inverter designer to easily test the Miller clamp and
rail-to-rail capability of the ACPL-H342/K342 gate drive
optocoupler. The evaluation board includes two separate
gate drive channels (one optocoupler per channel) making
it a half-bridge topology for driving directly the gates of
high-side and low-side IGBTs of a power inverter (such as
single-phase motor inverter or one phase of a 3-phase
motor inverter).
Features of the evaluation board as listed:
x Half-Bridge topology
x Footprints for bootstrap power supply configuration
x Works for IGBT TO-220 / TO-247 type
x Able to evaluate active Miller clamp and rail-to-rail
performance
x Footprints for PCB mounting terminal blocks for wire
connections to motor
x Example of good bypass capacitors layout
