2.3.3 Isolated Comparator (AMC23C15) Analog Output

AMC-AMP-200A-EVM AMC-AMP-200A-EVM Isolated Comparator (AMC23C15) Analog OutputFigure 2-4 AMC-AMP-200A-EVM Isolated Comparator (AMC23C15) Analog Output

Figure 2-4 shows the analog output circuit for the AMC-AMP-200A-EVM AMC23C15 signal chain.

The analog output of the AMC23C15 provides the overcurrent protection response of the circuitry.

The AMC23C15 output is accessible to the user through test-points OUT1 and OUT2. OUT1 connects to window comparator 1, adjustable threshold. OUT2 connects to window comparator 2, fixed threshold. OUT1 transitions from high to low at approximately ±288A input current with default configurations. OUT2 transitions from high to low at ±60mV at the input of the device. Resistors R15 and R16 are pullup resistors. Capacitors C21 and C22 serve as decoupling capacitors.
