Rohm has launched the BM6GD11BFJ-LB, an remoted gate driver optimized for 600-V-class GaN HEMTs in industrial gear corresponding to motors and server energy provides. When paired with GaN transistors, the single-channel driver maintains secure operation beneath high-frequency, high-speed switching situations.
The gadget ensures protected sign transmission by galvanically isolating the management circuitry throughout switching occasions with quick voltage rise and fall instances. Its 4.5-V to six.0-V gate drive vary and 2500-Vrms isolation score help a broad choice of high-voltage GaN units, together with Rohm’s 650-V EcoGaN HEMT. Low output-side present consumption—0.5 mA most—helps cut back standby energy and enhance total system effectivity.
The BM6GD11BFJ-LB makes use of proprietary on-chip isolation to cut back parasitic capacitance, enabling high-frequency operation as much as 2 MHz and lowering exterior part depend. Enhanced CMTI of 150 V/ns—reportedly 1.5× larger than standard merchandise—prevents malfunctions throughout quick GaN switching. A diminished minimal pulse width of 65 ns improves obligation cycle management, permitting secure, environment friendly operation at larger frequencies.
The BM6GD11BFJ-LB remoted gate driver is now obtainable by means of on-line distributors together with DigiKey and Mouser. Samples are priced at $4 every.
