When the input power or input signal is lost, the default output of a digital isolator with suffix F is low, while the default output without suffix F is high.
When the clamp function is not used, it is recommended to connect the VCLAMP pin to the driver output pin VOUT. If VCLAMP is connected to VEE, SLMi334 will lose its soft shutdown function when de saturation protection occurs.
It is necessary to pay attention to the parasitic parameters of the PCBA itself used. The working current of the power supply is greatly affected by the parasitic parameters at high frequencies, and we cannot only care about the external capacitance parameters. We need to evaluate the equivalent capacitance value of the PCBA board, which determines the size of the working current of the power supply at high frequencies
Both models do not have a VIO power supply, but the difference is that the input logic of SiLM1042 is TTL level, while the input logic of SiLM1044 is CMOS level, so the input voltage of SiLM1044 is higher
Disturbance to DIS can cause abnormal output. It is recommended that DIS be connected to GND1
