Typical Application Circuit

Figure 5. Zero-Crossing Detector

Logic-Level Translator

The open-drain comparators can be used to convert 5V

logic to 3V logic levels. The MAX9020 can be powered

by the 5V supply voltage, and the pullup resistor for the

MAX9020’s open-drain output is connected to the 3V

supply voltage. This configuration allows the full 5V

logic swing without creating overvoltage on the 3V logic

inputs. For 3V to 5V logic-level translations, connect the

3V supply voltage to VCC and the 5V supply voltage to

the pullup resistor.
