Si834xx Isolated Smart Switch

PublishTime：2021-11-23

●The Si834x provides four isolated high-side or low-side switches with low RON. These switches are ideal for driving resistive and inductive loads like solenoids, relays, and lamps commonly found in industrial control systems like Programmable Logic Controllers (PLC). Each switch is galvanically isolated for safety using Silicon Labs’ groundbreaking CMOS-based isolation tech-nology, offering better reliabiliand performance than the traditional optocoupler-based isolation,including high Common-Mode Transient Immunity (CMTI) over 100 kV/μs.
●The logic interface supports low-power 2.25 V MCUs, while the switches offer a wide supply range of 9 V – 32 V ideal for industrial voltage levels. The switches are capable of providing 0.7 A depending on load conditions. Each switch offers complete fault protection. An innovative multi-voltage clamp efficiently handles an unlimited amount of demagnetization energy (EAS).The over-current protection includes an Inrush Current Mode to drive loads like lamps. Addi-tionally, the device power supplies are monitored, and the switches are safely constrained or shutdown on faults.
●Eight diagnostics are reported through the logic interface, offering an unprecedented level of details and control. Diagnostics are configured, monitored, and cleared via the Serial Periph-eral Interface (SPI) or exposed on active-low, open-drain indicator pins for easy access and combination. Diagnostic communication is independent of switch control signals, with separate isolation channels and constant error checking, ensuring long-term reliability.
