ROHM Semiconductor Releases Innovative Isolated Gate Driver IC
ROHM Semiconductor Unveils Cutting-Edge Isolated Gate Driver IC
In a significant stride towards advancing power management technology, ROHM Semiconductor has launched the BM6GD11BFJ-LB, an isolated gate driver integrated circuit specifically engineered for 600V-class high-voltage GaN HEMTs. This product marks a pivotal development in enhancing the performance of electrical systems by enabling reliable operation under challenging high-frequency conditions.
Efficiency and Miniaturization: A Global Need
As global energy demands rise, the need for energy-efficient solutions is becoming crucial. Research indicates that motors and power supplies contribute to nearly 97% of global electricity consumption. To combat this excessive usage, industries are increasingly turning to technologies like SiC and GaN, which allow for enhanced control and conversion of power, leading to superior efficiency.
Innovative Technology Behind BM6GD11BFJ-LB
ROHM has drawn on its extensive expertise in creating isolated gate drivers for silicon and SiC technologies to design the BM6GD11BFJ-LB. This new IC represents the beginning of a series aimed at optimizing GaN devices, providing superior signal isolation from control circuits amidst rapid voltage transitions. This isolation is essential for maintaining operational integrity in fast-switching scenarios.
Advanced Features for Enhanced Performance
The BM6GD11BFJ-LB incorporates proprietary on-chip isolation technology that effectively diminishes parasitic capacitance, enabling impressive high-frequency operation of up to 2MHz. This advancement not only bolsters the energy efficiency of GaN devices but also reduces the required footprint for peripheral components, facilitating more compact designs.
Enhanced CMTI for Reliability
The driver boasts a Common-Mode Transient Immunity (CMTI) rating of 150V/ns, a significant increase of 1.5 times compared to traditional models. This enhancement helps mitigate malfunction risks that arise from the rapid switching speeds typical of GaN devices. Additionally, the reduced pulse width of just 65ns, which is 33% shorter than that of conventional drivers, ensures stable operation at elevated frequencies while optimizing power loss management.
Supporting a Variety of Applications
With a gate drive voltage range spanning from 4.5V to 6.0V, along with an impressive isolation voltage of 2500Vrms, the BM6GD11BFJ-LB is adept at handling an extensive array of high-voltage GaN devices, including ROHM’s latest 650V EcoGaN™ HEMT. The industry-leading low output-side current consumption, capped at just 0.5mA, is vital for reducing standby power and enhancing overall system efficiency.
Application Versatility
This innovative isolated gate driver IC finds applications across various sectors:
- Industrial Equipment: Ideal for power supplies utilized in PV inverters, energy storage systems, communication base stations, and industrial motors.
- Consumer Devices: Suited for enhancing performance in products such as AC adapters, PCs, TVs, refrigerators, and air conditioners.
Future Aspirations and Gate Driver IC Ecosystem
ROHM is committed to expanding its offerings of gate driver ICs that will complement its GaN device range, aiming to simplify application design and integration for its users. The BM6GD11BFJ-LB is available through major online distributors, with a competitive sample pricing of around $4.0 per unit, excluding tax.
