New Gate Drivers From Power Integrations Deliver Up to 5 A, Reducing System Complexity and Cost

Power Integrations » SID1102K

Boosters allow scalable drive up to 60 A peak gate current; full protection features included

Power Integrations introduced the newest member of its SCALE-iDriver™ IC family, SID1102K, a single-channel, isolated, IGBT and MOSFET gate driver in a wide-body eSOP package. Featuring a peak drive current of up to 5 A, the new part is able to drive 300 A switches without boosters; external boosters can be used to cost-effectively scale gate current up to 60 A peak. This device provides N-channel drive for both the low and high side booster MOSFET switches which reduces system cost, minimizes switching losses and increases power capability.

Power Integrations - SID1102K

Reinforced galvanic isolation is provided by Power Integrations’ innovative, solid insulator FluxLink™ technology which eliminates the need for optocouplers, improving reliability and ruggedness. SCALE-iDriver technology simplifies design and manufacturing by reducing BOM count; complete drivers can be built using a SID1102K IC and just eight external components. Devices deliver system-level protection features including under-voltage lock-out, rail-to-rail stabilized output voltage – from a single supply rail, high common-mode transient immunity and 9.4 mm creepage and clearance.

Key applications include UPS, standard AC drives and VFDs, photovoltaic/ solar systems, commercial air conditioners, DC chargers and welding equipment. Devices are available now priced at $1.52 in 10,000 piece quantities.
