MAX22217ATJY+

Overview

The MAX22217ATJY+ is a quad smart serial-controlled solenoid and motor driver manufactured by Analog Devices. It integrates four programmable half-bridges designed to drive inductive loads such as solenoids, DC motors, and relays. The device operates on a supply voltage ranging from 4.5 V to 36 V with a quiescent current of 7 mA. Each half-bridge provides an output current capability of 1 A. It features a TQFN-32 package and supports operation across a temperature range of -40°C to +125°C.

Feature Summary

• Supports flexible configuration via SPI or One-Time Programmable (OTP) registers for independent operation.
• Offers multiple drive modes including high-side/low-side single-ended, bridge-tied load (BTL), and channel paralleling.
• Provides advanced control methods such as voltage regulation, current regulation, and mixed control modes.
• Includes comprehensive diagnostic capabilities for plunger motion, inductance measurement, and real-time current monitoring.

Applications

• Driving switch solenoids
• Controlling DC motors
• Actuating proportional valves
• Operating bistable valves
• Switching relays

Procurement Notes

Verify the specific suffix ATJY+ against the official datasheet to confirm pinout and thermal characteristics. Ensure the ordering information matches the required package type and temperature grade. Confirm RoHS compliance status through the manufacturer's certification documents before finalizing procurement specifications.

Selection Notes

Select this component when a quad-channel driver with 1 A per bridge is required. It is suitable for applications needing precise current control and diagnostic feedback. Consider the MAX22216 if higher current capacity of 3.2 A per bridge is necessary instead of the 1 A provided by the MAX22217.

Part Context

This part belongs to the MAX2221 series of smart drivers. It is designed for industrial and automotive environments requiring robust control of inductive loads. The series emphasizes flexibility through configurable drive modes and extensive diagnostic features for system reliability.

Replacement Considerations

The MAX22216 is a compatible alternative within the same family offering higher current capacity. Verify pin compatibility and thermal performance differences between the two models before substitution.

FAQ

How can the configuration settings be preserved without continuous SPI communication?

Configuration data can be stored in the One-Time Programmable (OTP) registers, allowing the device to load settings automatically upon power-up for independent operation.

What protection mechanisms are included in the MAX22217?

The device includes overcurrent protection (OCP), overtemperature protection (OVT), and undervoltage lockout (UVM).
