Digital isolators are invaluable in many situations when electrical isolation protection is needed, and one such tool is the SI8736BC-ISR. This application field and working principle of the SI8736BC-ISR will be discussed here in order to gain insight into its capabilities and uses.

The main purpose of the SI8736BC-ISR is to provide efficient electrical isolation between two circuits. In this way, it helps protect circuits against electrical faults, noise, and other forms of interference. Its use of transformer-based electrical isolation makes it exceptionally reliable and tolerant of high-power applications up to 6000Vrms.

The core of the SI8736BC-ISR is an optically isolated digital signal driver that operates on a differential input. The input signal (DATA) is converted from a digital signal to an isolated analog signal which is then transmitted through the opto-coupler to the secondary side of the transformer. On the secondary side, the signal is amplified and converted back into a digital signal. To ensure proper operation, the device requires a power supply voltage of 3.3V and a maximum supply current of 6mA.

The SI8736BC-ISR offers a range of features that make it suitable for many applications. One such feature is a high-voltage transistor driver, which can be used to drive complementary high-side and low-side gate-controlled devices. Additionally, the digital isolator includes a directional switch which allows the input of two complementary signal inputs (A, B) that can be used to provide the required signal logic, as well as a control pin for configuration of the output signal direction.

The SI8736BC-ISR is ideal for use in a variety of applications, including motor control, power supplies, and embedded applications. In motor control, it can be used to isolate the high-voltage motor from the control circuit, ensuring reliable operation even in the presence of high noise levels. In power supplies, it can be used to isolate the power supply from the circuit to prevent damage from shorts or overloads. Finally, it can be used in embedded applications to allow for the transmission of signals across electrically noisy or hazardous environments.

The SI8736BC-ISR is an effective and reliable digital isolator, and its range of features make it suitable for a wide range of applications. By providing a high level of electrical isolation, it enables reliable operation at high voltages, even in the presence of electrical noise or other disturbances.
