Product details
Overview
MAX22217ATJY+T from Analog Devices is a quad-channel, serial-controlled 36V smart half-bridge driver optimized for solenoid and DC motor control. It delivers up to 1A full-scale current per channel, supports voltage/current regulation modes, integrates real-time current sensing and plunger movement detection, and operates across -40°C to +125°C ambient for industrial valve actuation.
For engineers reviewing the MAX22217ATJY+T datasheet, MAX22217ATJY+T pinout, MAX22217ATJY+T application, or MAX22217ATJY+T equivalent, this page provides verified technical context, diagnostic capability details, protection architecture, SPI/OTP configuration options, and validated alternative drivers for solenoid and proportional valve systems.
Technical Context
The MAX22217ATJY+T implements four independent programmable half-bridges with configurable high-side, low-side, or bridge-tied load (BTL) operation. Each channel supports voltage drive regulation (VDR) with internal supply compensation and current drive regulation (CDR) using closed-loop feedback with user-configurable PI gains.
It embeds a two-level sequencer for power saving, dithering (DITH) to mitigate static friction, ramp control (RAMP) for EMI reduction, fast demagnetization (DC_H2L), and integrated diagnostics including open-load detection (OL), inductance measurement, travel time monitoring, and digital current sense via SPI.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Channels | 4 independent half-bridges - enables simultaneous control of 4 solenoids or 2 H-bridges for dual DC motors |
| Max Full-Scale Current | 1A per channel - supports proportional valves and small DC motors requiring precise current-limited drive |
| VM Supply Range | 4.5V to 36V - compatible with 12V/24V industrial power rails and tolerant of automotive load-dump transients |
| Operating Temp | -40°C to +125°C - qualified for under-hood, factory automation, and harsh-environment embedded control |
| RON (HS) | 0.17Ω typical - minimizes conduction loss and thermal rise at 1A DC, enabling compact heatsink-free designs |
| RON (LS) | 0.43Ω typical (SNSF=10) - balances efficiency and current-sense accuracy for diagnostic-grade operation |
| Diagnostic Interface | SPI-accessible real-time current monitor, plunger movement flag, inductance measurement, and OL status - eliminates need for external ADCs or sensors |
Pinout & Package
TQFN32 (5mm × 5mm, 0.5mm pitch) package with exposed thermal pad - supports high-power density PCB layouts and efficient heat dissipation in space-constrained industrial modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VM | Main power input | Connects to 4.5V–36V supply rail; powers output stage and charge pump; requires local 10µF ceramic decoupling |
| VIO | Logic interface supply | Supplies 2.2V–5.25V to SPI and control logic; enables mixed-voltage system interfacing (e.g., 3.3V MCU with 24V load) |
| CS, SCK, SDI, SDO | SPI interface | 4-wire serial interface for register read/write; supports CRC error detection; allows dynamic reconfiguration during operation |
| ENABLE | Global enable input | Active-high logic control; places device in ultra-low-power sleep mode (4µA) when low; must be stable before VM ramp-up |
| FAULT | Open-drain fault indicator | Asserts low on OCP, OVT, UVM, or OL faults; supports wired-OR fault bus for multi-driver systems |
| STAT_ | Status monitor output | Configurable multifunction pin reporting channel-specific diagnostics (e.g., DPM, OL, current limit) via SPI-mapped status registers |
| OUT_A–OUT_D | Half-bridge outputs | Four high-current terminals; each connects directly to solenoid/motor winding; supports HS, LS, or BTL configurations per channel |
| CFP/CFN/VCP | Charge pump capacitors | External 100nF ceramic caps required for high-side gate drive; enables full N-channel MOSFET implementation without bootstrap limitations |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar solenoid and motor driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX22216ATJY+T | Higher 3.2A full-scale current per channel; identical pinout, SPI interface, and diagnostic features | Better suited for larger solenoids or higher-torque DC motors requiring >1A peak current | Select when load current exceeds 1A but same footprint and firmware compatibility are required |
| STSPIN840TR | Single-channel 60V driver with integrated current sense; lacks plunger detection, inductance measurement, and OTP storage | Targeted at cost-sensitive single-axis motion control, not multi-valve industrial systems | Choose only for simple on/off solenoid drive where advanced diagnostics and quad integration are unnecessary |
Compared with MAX22217ATJY+T, MAX22216ATJY+T offers higher current headroom in the same package, while STSPIN840TR reduces integration level and diagnostic capability - making MAX22217ATJY+T optimal for space-constrained, multi-valve systems demanding embedded health monitoring.

FAQ
What is the maximum continuous current capability of the MAX22217ATJY+T per channel?
The MAX22217ATJY+T supports up to 1A full-scale current per half-bridge channel under specified thermal conditions. At TA = 25°C, its DC current rating is 0.55A; the 1A figure represents the programmable full-scale limit in current drive regulation (CDR) mode, confirmed in the Electrical Characteristics table under "Overcurrent Protection Threshold" for SNSF[1:0] = "10". This value is maintained across the full -40°C to +125°C operating range with appropriate PCB thermal design.
Does the MAX22217ATJY+T support standalone operation without an external microcontroller?
Yes, the MAX22217ATJY+T supports standalone operation via its one-time programmable (OTP) registers. Configuration settings-including drive mode, current limits, ramp rates, and sequencer behavior-can be factory-programmed into OTP memory and automatically loaded at power-up. This eliminates the need for SPI initialization by an MCU, enabling autonomous valve control in safety-critical or MCU-less subsystems.
How does the Detection of Plunger Movement (DPM) function work in the MAX22217ATJY+T?
The DPM function in the MAX22217ATJY+T monitors real-time coil inductance changes during energization to detect mechanical plunger motion. It uses the integrated current sense and voltage measurement circuitry to compute inductance slope; a threshold-crossing event triggers the DPM flag in the status register. This occurs within 1ms of physical movement onset and requires no external sensors, enabling closed-loop verification of valve actuation in systems like fuel injectors or pneumatic cylinders.
Can the MAX22217ATJY+T drive a DC motor in H-bridge configuration?
Yes, the MAX22217ATJY+T supports bridge-tied load (BTL) operation by pairing two half-bridges per motor winding. Its datasheet confirms full-bridge control capability in Figure 2 and Section "Bridge-Tied Load Operation (Full Bridge)". Each channel's independent configuration allows complementary PWM generation, dead-time insertion, and current limiting - making it suitable for bidirectional 24V DC motor control in applications such as linear actuators and conveyors.
What protection features are integrated into the MAX22217ATJY+T?
The MAX22217ATJY+T integrates overcurrent protection (OCP) with blanking time, overtemperature protection (OVT), undervoltage lockout (UVM), open-load detection (OL), and fault reporting via the FAULT pin. All protections are hardware-based and operate independently of SPI communication. The FAULT pin asserts low on any detected fault condition and remains asserted until cleared via SPI register write or power cycle - ensuring fail-safe behavior in industrial control environments.
