Description
Sense Amplifier Output – an external resistor to V
Sense amplifier negative input
Sense amplifier positive input – biased internally at +V
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
