The SM36B-TP is a voltage-controlled voltage source (VCVS) intended for TVS (Transient Voltage Suppression) applications. It is an ideal IC for providing transient protection for digital and analog circuits, as well as for protecting against electrostatic discharge (ESD). The SM36B-TP works by providing voltage-controlled switching to limit the maximum voltage and reduce the energy from transient surges.

The SM36B-TP is a dual-channel device that can be used in a variety of applications. It provides a two-channel broadband protection from ESD pulse widths of up to 10 ms, and it can be configured to provide maximum voltage switching for up to three times. The SM36B-TP is designed to be used in equipment with a wide range of inputs including USB, UART, and CAN, as well as other digital and analog interfaces. It also is ideal for protecting sensitive and expensive electronic equipment from transient voltage due to lightning, vehicular and aircraft EMP, and other sources.

The working principle of the SM36B-TP is the comparison of the input voltage to the configured maximum voltage setpoint. When the input voltage exceeds the setpoint, the SM36B-TP uses voltage-controlled switching to limit the voltage level and reduce the energy from the surge. The SM36B-TP also has an adaptive voltage scaling (AVS) which adjusts the setpoint at regular intervals to match the current input voltage. This allows the SM36B-TP to constantly monitor the input and provide optimal protection.

The SM36B-TP features a very low quiescent current (<500µA) with a voltage range of 2.6V to 3.6V, making it suitable for battery-powered applications. It can withstand up to 60A of peak ESD current, and a wide operating temperature range of -40°C to +85°C. It is capable of resisting transients up to 8kV ESD. The SM36B-TP also has a low threshold voltage (VTH) of only 0.7V, which is suitable for applications with a low operating voltage.

The SM36B-TP is a versatile IC that provides robust protection from ESD and transients for a wide range of applications. Its low power draw and wide operating range make it well suited for battery-powered applications. Its low threshold voltage and high surge current capability make it suitable for use in digital interfaces. The ability to monitor the input voltage and adjust the setpoint makes the SM36B-TP an ideal IC for providing reliable protection.
