The MAX22216V is an AEC-Q100 qualified driver. It integrates four programmable 36V half-bridges. It is primarily intended to drive inductive loads such as on-off solenoid valves, DC motors, proportional valves, bistable valves, and relays. The MAX22216V is capable of up to 3.2AFS per half-bridge and operates from -40°C to +125°C ambient temperature.

The MAX22216V half-bridges support two different use cases. In the first case, configuration settings can be entered through a serial peripheral interface (SPI) and can be changed at any time. Alternatively, settings can be stored in one-time programmable (OTP) registers, which are loaded at power-up. This enables standalone operations. Registers are user-programmable. The OTP writing procedure must be executed in a factory under well-controlled temperature and voltage conditions.

Please see the Data Sheet for the full description.

The MAX22216V evaluation board is the MAX22216EVKIT. The MAX22216EVKIT populates the MAX22216 for evaluation purposes.

Product Details

The MAX22216-EVAL-KIT (MAX22216EVKIT) includes the MAX22216-EVAL board alongside the Eselsbruecke and Landungsbruecke boards, to be used together with the TMCL-IDE as part of the Analog Devices Inc. Trinamic TMCL ecosystem.

The MAX22216-EVAL evaluates the MAX22216, MAX22217, and MAX22216V in combination with the TRINAMIC evaluation board system or as a standalone board. It uses the standard schematic and offers several options to test different modes of operation. To evaluate the MAX22217, set SNSF[1:0] = "10" for all channels while in use.

Advanced diagnostic functions are available to improve system reliability and enable predictive maintenance. These include the detection of plunger movement (DPM), travel time measurement, inductance measurement, open load detection (OL), and real-time current monitoring through the serial peripheral interface (SPI).

The MAX22216, MAX22217, and MAX22216V feature a full set of protection circuits, including overcurrent protection (OCP), overtemperature protection (OVT), and undervoltage lockout (UVM). A fault indicator pin is asserted whenever faults are detected.

APPLICATIONS

  • Solenoid Valves and Relays
  • Real-Time Current Measurement
  • Proportional Valves
  • DC Motors
  • Digital-Output Interface
  • Bi-stable Latching Solenoid Valves
