FEATURES

) ■ Blocking voltage: VDRM / VRRM = 500V

t(s ■ Clamping voltage: VCL = 600V

uc ■ Nominal current: IT(RMS) = 0.8 A

d ■ Gate triggering current : IGT < 10mA

ro ■ Triggering current is sourced by the gate

P ■ Switch integrated driver

te ■ Drive reference COM connected to the SOT-223

le tab

so BENEFITS

b ■ Needs no external overvoltage protection.

- O ■ Enables the equipment to meet IEC61000-4-5

) standard.

t(s ■ Allows straightforward connection of several

SOT-223 devices on the same cooling pad.

uc ■ Reduces the switch component count by up to

d 80%.

ro ■ Interfaces directly with the microcontroller.

P ■ Eliminates any stressing gate kick back on the

microcontroller.

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.
