Mingjiada Electronics Supplies ST L6498DTR Single Chip Half Bridge High Side Gate Driver

Shenzhen Mingjiada Electronics Co., Ltd. — as a professional electronic component supplier, now offers the ST (L6498DTR) high-voltage high-side and low-side 2A gate driver. Manufactured using BCD6 ‘offline’ process technology, this device is specifically designed for driving medium-to-high power MOSFETs/IGBTs, capable of withstanding DC voltage rails up to 500V and transient voltages up to 600V.

01 Product Specifications
The L6498DTR is a single-chip half-bridge gate driver from STMicroelectronics, suitable for driving N-channel power MOSFETs or IGBTs.
Its high-side (floating ground) section is engineered to withstand DC voltage rails up to 500V and possesses 600V transient withstand capability, ensuring stable operation in harsh industrial environments.
The L6498DTR's logic inputs are CMOS/TTL-compatible (supporting 3.3V minimum), enabling direct interfacing with control units such as microcontrollers or DSPs to simplify system design.
Both outputs can sink 2.5A and deliver 2A output current, making the L6498DTR particularly suitable for medium-to-high power MOSFET/IGBT applications.
The integrated interlocking function prevents both outputs from being pulled high simultaneously. Both upper and lower driver stages feature independent under-voltage lockout protection circuits, preventing power switches from operating in inefficient or hazardous states.
The integrated bootstrap diode and all internal features simplify and compact application PCB design while helping reduce overall material costs, representing a significant advantage of the L6498DTR.

03 Core Product Features
High voltage withstand capability and robust immunity to interference are defining characteristics of the L6498DTR. This device features 600V transient withstand voltage and ±50 V/ns dV/dt immunity across the full temperature range, effectively countering voltage fluctuations and noise interference in industrial environments.
High-efficiency drive performance makes the L6498DTR an ideal choice for power switching applications. The device delivers 2A source current and 2.5A sink current capability, combined with a rapid 25ns switching time (1nF load), significantly reducing switching losses.
The L6498DTR's integrated design substantially simplifies external circuitry. On-chip bootstrap diodes, interlock functionality, and independent undervoltage lockout protection reduce external component count, lowering system cost and PCB footprint.
Flexible interface compatibility represents another advantage of the L6498DTR. Its 3.3V/5V TTL/CMOS inputs with hysteresis enable direct connection to diverse controllers, enhancing design flexibility.
The compact packaging makes the L6498DTR suitable for space-constrained applications. The 8-SOIC package facilitates high-density routing while delivering favourable thermal performance.

04 Wide Range of Applications
The L6498DTR is suitable for diverse industrial and consumer electronics applications:
In industrial automation, the L6498DTR can be employed in industrial drives, factory automation systems, and fan motor drives, providing reliable power switch control.
Power management systems represent another key application area for the L6498DTR, encompassing power supply units, DC-DC converters, and various uninterruptible power supplies (UPS).
Within domestic appliances, the L6498DTR can be employed in motor drives and electromagnetic induction heating systems, where its high reliability meets the extended service life requirements of household products.

The L6498DTR is also suitable for HID ballasts and welding equipment, where its high-voltage withstand capability ensures stable operation.
Emerging applications such as wireless chargers and industrial inverters represent further key deployment scenarios, with its fast switching characteristics enhancing system energy efficiency.
