In this article, we will introduce Panasonic MOSFET Drivers.
This product is positioned as a product related to Panasonic's PhotoMOS semiconductor relays.
PhotoMOS are semiconductor relays that adopt an LED for the input element and MOSFET for the output element, while MOSFET Drivers are a packaged device with the MOSFET output element removed.
Since an external MOSFET is assumed to be combined with the MOSFET Driver, a semiconductor relay function can easily be configured. Allowing the user to select the MOSFET component enables a wider variety of high powered MOSFET options allowing the output characteristics to be specific to the desired circuit.

MOSFET Drivers are...
A PhotoMOS packaged product with the MOSFET part removed. This allows the user to maintain the semiconductor relay function that best fits the application of the circuit by selecting another external MOSFET component with desired output characteristics tailored to the circuit design.
Product line-up (Unit: mm)
The difference compared to PhotoMOS
Because the MOSFET driver is designed to work with an external MOSFET selected by the user, more options for power MOSFET output characteristics are available when designing a circuit.
Here is a possible issue that can be resolved using the MOSFET Driver
[Before] Semiconductor relays that meet the required specifications are not available!!>
Semiconductor relays that meet the required characteristics are not available as standard products...
The expected volume needed is not large, so using custom products would be expensive...
[By using MOSFET Drivers ] - >MOSFET can be combined freely by using MOSFET drivers.
Using a MOSFET driver combined with a discrete MOSFET will achieve the desired characteristics on the output side!
Applications
Combined with a power MOSFET, circuits can achieve reduced MOSFET On-Resistance and increased operation speed suitable to applications found in a variety of markets.
Application Examples
Features of New Panasonic MOSFET Driver Products
Using a Si-MOSFET as the power MOSFET has become popular.
In addition, SiC (Silicon Carbide) MOSFET technology is rapidly expanding into applications in recent years beyond vehicles such as industrial usage.
In order to achieve High-output voltage and high-speed motion requirements commonly found in these applications, Panasonic has newly launched the MOSFET Driver High Output Voltage Type which meets high-power requirements and enables high-speed motion.
In this article, we provided an outline of Panasonic MOSFET Drivers.
Next time, we will present possible solutions to circuit designers in dealing with issues related to combinations with MOSFET components.
