Description

The SIC1182K is a single channel gate driver in an eSOP-R16B package

for SiC MOSFETs. Reinforced galvanic isolation is provided by Power

Integrations’ revolutionary solid insulator FluxLink technology. Up to

±8 A peak output drive current enables the product to drive devices

with nominal currents of up to 600 A (typical).

Additional features such as undervoltage lock-out (UVLO) for

primary-side and secondary-side and rail-to-rail output with tempera-

ture and process compensated output impedance guarantee safe

operation even in harsh conditions.

Furthermore, this gate driver IC comes along with a new feature, com-

bining short-circuit protection (at and during turn-on phase) as well as

overvoltage limitation by advanced active clamping (at turn-off phase)

through a single sensing pin. In case driven semiconductor provides

a current-sense terminal, an adjustable over-current detection can be

realized.
