Isolators - Gate Drivers

PC929 is an isolated gate driver, using transformer-based galvanic isolation technology. It operates from single +3.5V to +24V power supply and provides an isolated 5V logic supply. It provides an enhanced capability of driving a wide range of isolated gate drivers, such as the GateMote and Isolator-V7 units. With 10mA of continuous source/sink current per channel, and a maximum of 10kV isolation voltage, it offers high reliability and performance.

PC929 isolates two levels of input signals from each other. It consists of two converters, one for the input signals and one for the output signals. The signal converter on the input side transforms the two input levels into a single signal level. The signal converter on the output side converts the single signal level into the two output levels, which are used to drive the externally connected gate driver. In between the two converters is a transformer, which allows the output signals to be completely independent of the input signals, isolating them from any potential interference.

The output of PC929 can drive two types of gate drivers: Open-Drain and Push-Pull. Open-Drain output drivers are used for applications requiring low-power consumption and easy connection to external systems. Push-Pull drivers are used for applications that require higher drive currents and faster response times. The PC929 can reach up to 10mA of continuous source/sink current for each output channel and 10kV of isolation voltage.

The PC929 also features a number of configurable features which allow it to be adapted to different types of I/O signals. It supports logic levels from +3.5V to +24V, both sinking and sourcing. It also has a selectable pull-up/pull-down feature which can be used to ensure compatibility with different I/O levels. Additionally, the PC929 has adjustable dead time settings for both the sink and source channels. This allows for better signal integrity and improved system performance when operating at high frequencies.

In summary, the PC929 is an isolated gate driver providing galvanic isolation technology with up to 10kV isolation voltage and 10mA of continuous current. It offers a variety of features, such as adjustable dead time, pull-up/pull-down, and two output types, ensuring a high level of flexibility for various I/O signals. With its robust design and reliability, PC929 is a great choice for demanding applications that require high-end isolated gate drivers.
