SIC1182K Power Integrations

SIC1182K SCALE-iDriver Family Up to 8 A Single Channel SiC MOSFET Gate Driver Providing Advanced Active Clamping and Reinforced Isolation up to 1200 V Product Highlights Description Highly Integrated, Compact Footprint The SIC1182K is a single channel gate driver in an eSOP-R16B package 8 A peak gate output current for SiC MOSFETs. Reinforced galvanic isolation is provided by Power Integrated FluxLink technology providing reinforced isolation Integrations revolutionary solid insulator FluxLink technology. Up to Advanced Active Clamping 8 A peak output drive current enables the product to drive devices UVLO primary and secondary side with nominal currents of up to 600 A (typical). Over-current fault turn-off Additional features such as undervoltage lock-out (UVLO) for Short-circuit current fault turn-off primary-side and secondary-side and rail-to-rail output with tempera- Rail-to-rail stabilized output voltage ture and process compensated output impedance guarantee safe Unipolar supply voltage for secondary-side operation even in harsh conditions. Suitable for 600 V / 650 V / 1200 V SiC MOSFET switches Up to 150 kHz switching frequency Furthermore, this gate driver IC comes along with a new feature, com- Propagation delay jitter 5 ns bining short-circuit protection (at and during turn-on phase) as well as -40 C to +125 C operating ambient temperature overvoltage limitation by advanced active clamping (at turn-off phase) High common-mode transient immunity through a single sensing pin. In case driven semiconductor provides eSOP package with 9.5 mm creepage and clearance a current-sense terminal, an adjustable over-current detection can be realized.

Functional Block Diagram. VISO Pin (Pin 14) Pin Functional Description This pin is the input for the secondary-side positive supply voltage. VCC Pin (Pin 1) COM Pin (Pin 15) This pin is the primary-side supply voltage connection. This pin provides the secondary-side reference potential. GND Pin (Pin 3-6) GL Pin (Pin 16) This pin is the connection for the primary-side ground potential. This pin is the driver output-sinking current (turn-off) connection. All primary-side voltages refer to this pin. IN Pin (Pin 7) This pin is the input for the logic command signal. SO Pin (Pin 8) This pin is the output for the logic fault signal (open drain). NC Pins (Pin 9) This pin must be un-connected. Minimum PCB pad size for soldering is required. VEE Pin (Pin 10) Common (MOSFET source) output supply voltage. SNS Pin (Pin 11) This pin is the sense input detecting short-circuit events at turn-on and limiting overvoltages at turn-off. VGXX Pin (Pin 12) This pin is the bootstrap and charge pump supply voltage source. GH Pin (Pin 13) Figure 4. Pin Configuration.
