DI4A-05W21 Isolated Gate Driver for Power Electronics Applications

DI4A-05W21 Isolated Gate Driver

DI4A-05W21 has been introduced as a new member of the Lentark gate driver family.

The module is a two-channel isolated gate driver developed for MOSFET, IGBT and SiC MOSFET switching applications. It provides 4 A peak source current and 6 A peak sink current, making it suitable for applications where strong gate charging and discharging capability is required.

Programmable Dead-Time Structure

DI4A-05W21 includes a programmable dead-time feature.

The dead-time value can be adjusted over a wide range, allowing the module to adapt to different switching requirements. This is especially useful in complementary switching structures where both switching devices must not conduct at the same time.

By defining a controlled delay between transitions, the module helps support safer switching behavior in half-bridge and related power electronics circuits.

Configurable Output Operation

The output structure of DI4A-05W21 can be configured in different ways.

The module can be used as two independent low-side drivers or as a half-bridge driver with high-side and low-side outputs. This flexibility makes it useful in driver experiments, prototype switching circuits and power electronics development work.

Isolation and Switching Performance

The module is based on an isolated gate driver structure.

It provides high common-mode transient immunity, reinforced isolation performance and fast switching capability. These features are important in applications where noise immunity, timing accuracy and galvanic isolation directly affect system reliability.

Typical Application Areas

DI4A-05W21 can be used in applications that require isolated MOSFET, IGBT or SiC MOSFET gate driving.

Typical application areas include:

· Battery charging applications

· Isolated DC-DC and AC-DC power supplies

· Server, telecom and industrial infrastructure systems

· Motor driver applications

· LED lighting applications

· DC-AC solar inverters

· Induction heating applications

· UPS systems

· R&D and laboratory test setups

Conclusion

DI4A-05W21 adds a configurable isolated gate driver option to the Lentark gate driver family. With programmable dead-time, two-channel output structure, 4 A source current, 6 A sink current and half-bridge support, it provides a practical driver platform for power electronics development and switching circuit applications.
