The MAX14821ETG+ is an IO-Link device transceiver in 24 pin TQFN package. This transceiver is suitable for IO-Link devices and 24V binary sensors/actuators. All specified IO-Link data rates are supported. In IO-Link applications, the transceiver acts as physical layer interface to a microcontroller running data link layer protocol. Additional 24V digital inputs and outputs are provided. Two internal linear regulators generate common sensor and actuator power requirements (5V and 3.3V). Onboard C/Q and DO drivers are independently configurable for push-pull, high side (PNP) or low side (NPN) operation. The device detects IO-Link C/Q wake-up condition and generates wake-up signal on active-low WU output. The SPI interface allows configuration and monitoring of the devices. The C/Q and DO drivers are specified for sourcing/sinking up to 100mA. The MAX14821 is used in IO-Link sensors and IO-Link actuators.
