SI82394BB4-IS1 isolators are power gate drivers designed to offer superior performance, reliability and ease-of-use in a fashion that is suitable for the most demanding switch-mode power supplies (SMPS) and inverter designs.

As isolators, their primary purpose is to electrically separate two electrical systems by providing galvanic isolation to ensure that current does not flow between the two systems, thereby preventing ground loops and other unwanted phenomena. In essence, these devices work in a similar fashion to opto-couplers and other optical isolators, but without the need for any light-based components.

The SI82394BB4-IS1 isolator is designed to be used in a variety of applications, such as motor control and general-purpose switching, where the driver functions as a power switch. It is suitable for both isolated and non-isolated power supply applications. These drivers enable the application of high voltage and high switching frequencies in a single device, allowing the system designer to reduce component count and the system size.

In particular, the SI82394BB4-IS1 offers two sets of outputs – high side switching outputs and low side switching outputs. These allow the designer to utilize the device for both high side and low side switching applications. The rated current is 4A, making it suitable for applications that require both high power and high switching frequencies. Additionally, the device is rated for a maximum operating voltage of 5.5V, enabling its use in wide range of applications.

To further complement its features, the driver includes a slew rate control pin that gives the user the flexibility to lower the maximum current in high side mode if needed. This feature combined with its low on state resistance (typically 200 milliohms) offers increased energy efficiency and reduces the heat losses associated with switching power.

On the electrical safety side, the SI82394BB4-IS1 features an under-voltage lockout (UVLO) function which helps protect against excessive switching losses. It also integrates robust ESD protection, common-mode transient immunity, and a fault-output protection circuit to ensure reliable operation in the harshest operating environments.

Moreover, the device is designed to be used in automotive applications, meeting the stringent requirements of the most demanding automotive applications. It also meets the requirements of the ISO 26262 ASIL C functional safety standard, allowing it to be used in safety-critical systems. Additionally, it supports industrial temperature ranges of -40°C to +85°C.

As a result, the SI82394BB4-IS1 is widely used in a variety of applications, including automotive, industrial, energy, and consumer electronics. Its attractive features, combined with its superior performance, make it the ideal device for the most demanding switch-mode power supplies and inverter designs.
