MSN14827
MSN14827 is a dual-driver IO-Link device transceiver featuring small package size and low power consumption. It enables industrial bidirectional point-to-point communication via the IO-Link interface, complies with PHY2 (3-wire connection), and supports COM1 (4.8 kbaud), COM2 (38.4 kbaud), and COM3 (230.4 kbaud) modes. It also integrates auxiliary channels for digital output (DO) and digital input (DI).
The MSN14827 incorporates two low-power drivers with reverse‑polarity protection, as well as 5 V and 3.3 V linear regulators for low‑noise analog/digital supplies. The device offers a flexible control interface: in addition to an SPI interface for configurability and extended diagnostics, it provides a multiplexed UART/SPI option that allows a single serial microcontroller to share both SPI and UART interfaces. Furthermore, fault reporting and internal protection are provided against undervoltage, overcurrent, and overtemperature conditions.
