Functional Description
Snubber to reduce voltage ringing when the device turns off
Output (Load) Capacitor
Output (Load) Capacitor
To indicate a fault exists when it is on
Bias resistor optional, can be used to replace the internal resistor. Remove R3, and R4 if
the this option is desired.
Controller bias input through internal resistor.
LED current limit resistor, selected to operate at 3.3V and 5.0V logic voltage. Replace R5
and R6 with the proper resistor value for different logic voltage.

Test Procedure:
Initial Test Set Up
PI2126-EVAL1 designed with two input bias
configurations, VC biased via external resistors (R1 and
R2) or VC biased via the internal resistor (VR input pin,
R_Bias=420Ω ±30%). PI2126-EVAL1 is configured with
the internal bias resistors, R3 and R4 are installed
where R1 and R2 were not installed. If external VC
bias resistor with higher accuracy is desire, remove R3
and R4 before installing R1 and R2.
