MAXREFDES278 IO-Link® 8-Channel Solenoid Actuator

Analog Devices MAXREFDES278 IO-Link® 8-Channel Solenoid Actuator is a reference design based on the MAX22514 IO-Link Transceiver. The MAXREFDES278 demonstrates an 8-Channel Solenoid Actuator using the MAX22200 1A Octal Integrated Serial-Controlled Solenoid Driver with Integrated FETs. This reference design has two power options. It can be powered through the IO-Link master directly, delivering up to 800mA total load, or for higher currents, external power can be provided using an external source. To ensure no current flows back to the IO-Link master and the IO-Link portion is always powered, this design uses the MAX17608 Current Limiter, which features overvoltage (OV), under-voltage (UV), and reverse protection.
