Si83401BAA-IF - Isolated Smart Switch

Datasheet Summary

Description

The Si834x provides up to 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).

Features

  • High-side or low-side switch.
  • Logic Supply: 2.25 V.
  • 5.5 V.
  • Switch Supply: 9 V.
  • 32 V.
  • Fast (10 µs) update rate.
  • High continuous current and low RON - 4 channels: 700 mA (155 mΩ) - 2 channels: 1.25 A (78 mΩ) - 1 channel: 2.5 A (41 mΩ).
  • Unique multi-voltage output clamp - Unlimited demagnetization (EAS) - Efficient and fast turn-OFF.
  • Inrush Current Mode: 8 A for 20 ms.
  • Current-limited overload protection.

DATA SHEET Si834x Isolated Smart Switch Data Sheet Description The Si834x provides up to 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 Skyworks’ groundbreaking CMOS-based isolation technology, offering better reliability and 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.
