TIP Ground Detect Input.
Used to detect current flowing in TIP for supporting ground start applications.
TIP Ground Detect Enable Output.
Control signal for the ground detect relay. Used to support ground start applications.
Reset Input.
An active low input that is used to reset all control registers to a defined, initialized
state. Also used to bring the Si3050 out of sleep mode.
Isolation Capacitor 2A.
Connects to one side of the isolation capacitor C2. Used to communicate with the
line-side device.
Isolation Capacitor 1A.
Connects to one side of the isolation capacitor C1. Used to communicate with the
line-side device.
Regulator Voltage Reference.
This pin connects to an external capacitor and serves as the reference for the internal
voltage regulator.
Digital Supply Voltage.
Provides the 3.3 V digital supply voltage to the Si3050.
Ground.
Connects to the system digital ground.
Serial Port Bit Clock Input.
Controls the serial data on SDO and latches the data on SDI.
SDI Passthrough Output.
Cascaded SDI output signal to daisy-chain the SPI interface with additional devices.
