Gate drivers reduce system complexity and cost
The latest member of Power Integrations’ Scale-iDriver IC family, the SID1102K, has been announced.
The single-channel, isolated, IGBT and MOSFET gate driver is offered in a wide-body eSOP. The SID1102K has a peak drive current of up to 5.0A, and is able to drive 300A switches without boosters. External boosters can be used to cost-effectively scale gate current up to 60A peak, adds Power Integrations.
The gate driver provides n-channel drive for both the low and high side booster MOSFET switches. This reduces system cost, minimises switching losses and increases power capability, claims Power Integrations.
Reinforced galvanic isolation is provided by Power Integrations’ solid insulator FluxLink technology which eliminates the need for optocouplers, to improve reliability and ruggedness. Scale-iDriver technology simplifies design and manufacturing by reducing bill of materials 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 stabilised output voltage – from a single supply rail, high common-mode transient immunity and 9.4mm creepage and clearance.
Target applications for the SID1102K include uninterruptible power supplies, standard AC drives and VFDs, photovoltaic / solar systems, commercial air conditioners, DC chargers and welding equipment. Devices are available now and technical support for SID1102K ICs is available from the Power Integrations website.
