Analog Devices / Maxim Integrated MAX22200 Solenoid & Motor Driver

Analog Devices Inc. MAX22200 Solenoid and Motor Driver is an octal 36V serial-controlled solenoid driver. ADI MAX2220 features each channel with a low impedance (200mΩ typical) push-pull output stage. It has a sink-and-source driving capability with up to 1ARMS driving current. The serial interface (SPI) supports daisy-chain configurations is provided to individually control each channel. The device half-bridges are configured as low-side drivers or as high-side drivers. Moreover, pairs of half-bridges can be paralleled to double the driving current or can be configured as full-bridges to drive up to four latched valves (bi-stable valves) or four brushed DC motors.
