Isolators, also known as isolation amplifiers, purpose to provide an electrically separated signal that can be transmitted over some distance. Isolated signals ensure that there is no direct connection between the input and output signals in the isolator. Isolators offer zero overlap between the input and output signals. Additionally, isolated signals eliminate the risk of ground loops which can cause inaccurate or distorted signals and reduce the system malfunction when transferring signals through long distances between two electrically isolated circuits. Isolation amplifiers can also be used to increase the output impedance of the signal, for impedance matching, or for signal conditioning.

On the other hand, gate drivers are used to significantly increase the electrical power that is transmitted from the input to the output. A gate driver is a device that amplifies the input signal, and helps reduce losses in terms of power. Gate drivers are used in both digital and analog amplifiers, as they increase the accuracy and range of signals passing from the input to the output. Additionally, these drivers provide an ideal environment for signal conditioning, as they reduce noises and distortions.

The SI8236BA-D-IMR is an example of a high-performance and cost-effective gate driver isolator available in a small package. This device integrates all the necessary components required for isolating and driving a gate or an IGBT. It provides an easy solution for implementing an isolated gate driver for medium or high-voltage applications. It features a high-voltage level to meet the necessary requirements of gate driving applications up to the maximum rating of 5,000 V peak. It operates at a maximum of 2.5A source output current and 2.0A sink output current.

This device helps to reduce time to market for applications that require isolation from the power circuit, such as in motor drives and industrial automation. It provides immunity from electromagnetic interference (EMI) which helps in stabilizing the drive circuit. In terms of EMI, this device eliminates the need for line-by-line filtering and balancing of the power system, resulting in improved system reliability and safety. The dual-channel isolated supply pins make it the perfect solution for those applications where the drivers need to be powered from two channels.

Additionally, the SI8236BA-D-IMR features a push-pull output configuration which helps to reduce signal switching times up to 90%. This device also has a dual-channel input voltage range of 1.2V-5V, with an output voltage range of ±15V. It also has a low stand-by current consumption of 5mA typical, and a maximum switching frequency of 57MHz.

The SI8236BA-D-IMR is an ideal solution for applications that require high speed and high resolution signal transfer. This device helps in reducing the time that it takes for a signal to reach its destination, while still preserving the signal accuracy and quality throughout the transfer. Its gate driver isolation offers a high degree of protection against over-voltage and transients, and its noise immunity makes it suitable for noisy environments. Additionally, it offers a wide operating temperature range of -40C to 85C, making it suitable for a variety of applications.
