This reference design demonstrates a robust interface to EnDat 2.2 Encoders. That shows EMC immunity, particularly immunity against fast transients such as inverter switching noise. The Encoder supply voltage is configurable and integrates protection against short circuit to prevent damage due to cable short or miss wiring and diagnostic feedback to detect the fault. The logic interface supports 3.3V down to 1.8V I/O. The design is compatible to TI LaunchPad™ development kit for easy evaluation of EnDat2.2 with the C2000™ MCU. This design has been tested up to 100-m cable length with several EnDat 2.2 encoders.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
