Typical application description
The ACST10 device has been designed to control medium power load, such as AC motors
in home appliances. Thanks to its thermal and turn off commutation performances, the
ACST10 switch is able to drive, with no turn off additional snubber, an inductive load up to
10 A. It also provides high thermal performances in static and transient modes such as the
compressor inrush current or high torque operating conditions of an AC motor. Thanks to its
low gate triggering current level, the ACST10-7S can be driven directly by an MCU through
a simple gate resistor as shown Figure 15.
