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
