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.
FEATURES
■ Blocking voltage: VDRM / VRRM = 500V
■ Clamping voltage: VCL = 600V
■ Nominal current: IT(RMS) = 0.8 A
■ Gate triggering current : IGT < 10 mA
■ Triggering current is sourced by the gate
■ Switch integrated driver
■ Drive reference COM connected to the SOT-223 tab
BenefitS
■ 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.
MAIN APPLICATIONS
■ AC on-off static switching in appliance & industrial control systems
■ Drive of low power high inductive or resistive loads like:
- relay, valve, solenoid, dispenser
- pump, fan, micro-motor
- low power lamp bulb, door lock
