Description

Sense Amplifier Output – an external resistor to VFB sets the IFAULT threshold

Sense amplifier negative input

Sense amplifier positive input – biased internally at +VS/2

Substrate ground for all circuitry

Anode of internal diode connected to supply voltage

Supply input for RV4141A circuitry

Output for triggering external SCR when a fault is detected

An external capacitor to ground sets the delay time for a ground fault to be present before
