Gate drivers deliver up to 5 A

18 April 2018 Power Electronics / Power Management

Power Integrations introduced the newest member of its SCALE-iDriver IC family: the 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, minimises switching losses and increases power capability. Reinforced galvanic isolation is provided by Power Integrations’ 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, as 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 stabilised 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.
