DESCRIPTION
The ACS108 belongs to the AC line switches built
around the ASD™ concept. This high performance
device is able to control an 0.8 A load device.
The ACS™ switch embeds a high voltage clamping
structure to absorb the inductive turn-off energy
and a gate level shifter driver to separate the digital
controller from the main switch. It is triggered with a
negative gate current flowing out of the gate pin.

AC on-off static switching in appliance & indus-
trial control systems
Drive of low power high inductive or resistive
loads like
- relay, valve, solenoid, dispenser
- pump, fan, micro-motor
- defrost heater
Blocking voltage: V
Clamping voltage: V
Nominal current: I
Gate triggering current : I
Triggering current is sourced by the gate
Switch integrated driver
Drive reference COM connected to the SOT-223
tab
Needs no external overvoltage protection.
Enables the equipment to meet IEC61000-4-5
standard.
Allows straightforward connection of several
SOT-223 devices on the same cooling pad.
Reduces the switch component count by up to
80%.
Interfaces directly with the microcontroller.
Eliminates any stressing gate kick back on the
microcontroller.
