The MAX22200 is an octal 36V serial-controlled solenoid driver. Each channel features a low impedance (200mΩ typ) push-pull output stage with sink-and-source driving capability and up to 1ARMS driving current. A serial interface (SPI) that also supports daisy-chain configurations is provided to individually control each channel.

The device half-bridges can be configured as low-side drivers or as high-side drivers. Moreover, pairs of halfbridges 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.

Two control methods are supported: voltage drive regulation (VDR) and current drive regulation (CDR). In VDR, the device outputs a PWM voltage in which the duty cycle is programmed using SPI. For a given supply voltage and solenoid resistor, the output current is proportional to the programmed duty cycle. In CDR, an internal integrated lossless current sensing (ICS) circuit senses the output current and compares it with an internal programmable reference current.

For optimal power management in solenoid drive applications, the excitation drive level (IHIT), the hold drive level (IHOLD), and the excitation drive time (tHIT) can be individually configured for each channel.

The MAX22200 features a full set of protections and diagnostic functions. This includes overcurrent protection (OCP), thermal shutdown (TSD), undervoltage Lockout (UVLO), open-load detection (OL), and detection of plunger movement (DPM). A fault indication pin (active-low FAULT) signals fault events and diagnostic information is stored in the FAULT register.

Due to the flexibility of use, the serial interface control, the high efficiency, and the small package, the MAX22200 is particularly well-suited for solenoid driver applications (valve control, relays control etc.) in which low power consumption and high level of integration are required.

The MAX22200 is available in a compact 5mm x 5mm, 32-pin TQFN package and operates over the temperature -40°C to +85°C range.
