PMIC - Gate Drivers

IXDN404PI is an isolated, high-side power switch IC designed to control the power supply of a wide range of applications including microcontrollers, opto-electronic circuits, signal isolators, and relays. This device is compatible with most digital microcontrollers and can be used as a single channel, dual channel, or quad channel output for operation in any combination of 8-bit, 16-bit, and 32-bit applications. IXDN404PI is packaged in a non-isolated 6-pin package that is RoHS compliant.

Application Field

IXDN404PI is ideal for use in a wide range of applications such as:

• Telecommunications and networking
• Industrial equipment
• Automotive and military applications
• Computer peripherals
• Instrumentation and Audio equipment
• Medical instrumentation

This gate driver device is a practical and cost-effective solution for managing the power supply of a range of applications, including single-output and multi-output systems.

Working Principle

IXDN404PI is based on the principle of sourcing current and can be configured in different ways, depending on the application. When an external VCx+ is connected to the driver, the IXDN404PI will draw a constant current from it, up to a maximum of 600mA, and this current is used to drive the downstream applications. The device has a high-side driver stage, which is the interface between the supply voltage and the logic of the device. This allows the device to monitor the output voltage and adjust itself accordingly.

IXDN404PI also features adjustable current limiting and a shutdown feature that allows the user to turn off the device in the event of an overload. This device also has a low-side driver stage, which is used to control the power supplied to the downstream components. The IXDN404PI can sense the load current and adjust the switch current and voltage at the same time. This allows for more efficient and accurate power delivery.

The IXDN404PI also has a built-in timer circuit, which can be used to delay the switching of the power supply. This timer circuit is highly configurable and can be set to any desired time period.

Conclusion

The IXDN404PI is a high-side power switch IC that is ideal for use in a wide range of applications. It is capable of driving the power supply of one or more downstream components, and features adjustable current limiting, a shutdown feature, and a timer circuit. This device is also RoHS compliant and is available in a non-isolated 6-pin package.
