Product details
Overview
MAX22217ATJY+ from Analog Devices is a quad-channel, serial-controlled 36V smart solenoid and motor driver IC with integrated current regulation, diagnostic functions, and four programmable half-bridges. It delivers up to 1A full-scale output per channel, supports voltage/current drive modes, operates from −40°C to +125°C, and targets industrial valve control and DC motor actuation.
For engineers reviewing the MAX22217ATJY+ datasheet, MAX22217ATJY+ pinout, MAX22217ATJY+ application, or MAX22217ATJY+ equivalent, key selection criteria include its 1A full-scale current capability, TQFN32 5mm × 5mm package, SPI/OTP configuration flexibility, real-time current monitoring, and advanced diagnostics including plunger movement detection and inductance measurement.
Technical Context
The MAX22217ATJY+ implements four independent half-bridge output stages 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 programmable PI gains.
It integrates a two-level sequencer for power saving, ramp control for EMI reduction, dithering to counteract static friction, fast demagnetization (DC_H2L), and a DC-motor current limiter. Diagnostic features include open-load detection, real-time current monitoring via SPI, travel time measurement, and inductance-based plunger movement detection (DPM).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Channels | 4 independent half-bridges - enables simultaneous control of multiple solenoids or motor phases without external logic. |
| Full-Scale Current | 1A per channel - sufficient for proportional valves, bi-stable solenoids, and small DC motors up to ~24W at 24V. |
| Supply Voltage Range (VM) | 4.5V to 36V - compatible with 12V/24V industrial power rails and tolerant of automotive load-dump transients. |
| Operating Temperature | −40°C to +125°C ambient - qualified for under-hood, factory automation, and harsh-environment applications. |
| On-Resistance (HS/LS) | RON(HS) ≤ 0.33Ω, RON(LS) ≤ 0.83Ω (MAX22217) - ensures <1W conduction loss at 1A, supporting thermally constrained PCB layouts. |
| Diagnostic Coverage | DPM, OL, inductance measurement, real-time current monitor - enables predictive maintenance and closed-loop system validation without external sensors. |
| Interface | SPI with optional CRC - allows deterministic configuration, status readback, and fault reporting in safety-critical systems. |
Pinout & Package
The MAX22217ATJY+ is housed in a thermally enhanced TQFN32 (5mm × 5mm, 0.5mm pitch) package with exposed thermal pad (EP), optimized for high-power density and efficient heat dissipation in compact industrial modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VM | Main power supply input | Accepts 4.5V–36V; powers output stage and charge pump - requires local bulk and ceramic decoupling near pin. |
| VIO | Logic I/O supply | 2.2V–5.25V interface rail; sets logic thresholds for SPI and control pins - isolates digital noise from analog/power domains. |
| ENABLE | Global enable input | Active-high logic control; asserts nap mode when low - enables system-level power sequencing and fail-safe shutdown. |
| SCK/CS/SDI/SDO | SPI interface signals | Standard 4-wire SPI with chip select; supports daisy-chaining and CRC-protected transactions for robust configuration. |
| FAULT | Open-drain fault indicator | Asserts low on OCP, OVT, UVM, or OL - directly drives LED or microcontroller interrupt without external pull-up. |
| STAT_ | Status monitor output | Configurable multifunction pin (via registers) for real-time current, PWM duty cycle, or VM voltage monitoring - reduces BOM count vs. discrete ADCs. |
| OUT1–OUT4 | Half-bridge output terminals | Four independent high-/low-side outputs - support single-ended, BTL, or paralleled 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 and low RON. |
Key Features
| Feature | Design Value |
|---|---|
| Voltage/Current Drive Regulation (VDR/CDR) | Selectable per channel; VDR compensates for VM variation, CDR enables precise 1A current control with configurable PI loop for dynamic response and steady-state accuracy. |
| Integrated Plunger Movement Detection (DPM) | Uses inductance change during coil energization to detect mechanical actuation - eliminates need for external position sensors in valve monitoring. |
| Ramp Control (RAMP) & Dither (DITH) | Programmable slew rate (100–800 V/µs) and sine-wave dithering reduce acoustic noise and stiction in proportional solenoids and precision actuators. |
| Fast Demagnetization (DC_H2L) | Shorts output to ground during turn-off to accelerate magnetic field collapse - cuts solenoid release time by >30% versus passive decay. |
| Real-Time Digital Current Monitor | 12-bit I_MONITOR output via SPI - provides calibrated current readings (±5% accuracy) for closed-loop control and stall detection without shunt resistors. |
| One-Time Programmable (OTP) Configuration | Factory-programmed startup settings enable stand-alone operation - removes dependency on host MCU for basic functionality in safety-critical or boot-critical systems. |

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+ | Higher full-scale current (3.2A vs. 1A), lower RON(LS) (0.33Ω vs. 0.83Ω), same pinout and register map. | Better suited for larger solenoids, higher-power DC motors, or parallel-channel configurations demanding >1A per channel. | Select MAX22216ATJY+ when peak load current exceeds 1A or thermal headroom is limited; otherwise MAX22217ATJY+ offers better cost/performance for 0.5–1A loads. |
| TLE9201SG | Single-channel 40V half-bridge, no integrated current sensing or DPM; requires external shunt and MCU-based diagnostics. | Lacks multi-channel integration and advanced diagnostics - suitable only for simpler, lower-channel-count designs with external processing. | Choose TLE9201SG only if system already uses distributed single-channel drivers and does not require plunger detection or real-time current monitoring. |
Compared with MAX22216ATJY+, the MAX22217ATJY+ trades peak current capability for lower RON mismatch and tighter thermal management in space-constrained modules; versus TLE9201SG, it delivers integrated diagnostics and quad-channel consolidation, reducing component count and firmware complexity in valve-control systems.

FAQ
What is the maximum continuous output current per channel for the MAX22217ATJY+?
The MAX22217ATJY+ supports up to 1A full-scale current per half-bridge channel under typical conditions (TA = 25°C, VM = 24V). Its actual continuous current capability depends on PCB thermal design and ambient temperature - at +125°C ambient, derating limits sustained current to approximately 0.55A DC per channel, as specified in the Electrical Characteristics table.
Does the MAX22217ATJY+ support both SPI and standalone (OTP) configuration modes?
Yes, the MAX22217ATJY+ supports dual configuration methods: real-time SPI programming for dynamic reconfiguration, and one-time programmable (OTP) register storage for factory-set parameters that load automatically at power-up. OTP programming requires controlled factory conditions and is irreversible, enabling secure, MCU-free operation in safety-critical systems.
How does the plunger movement detection (DPM) function work in the MAX22217ATJY+?
The MAX22217ATJY+ implements DPM by measuring inductance changes during coil excitation using its integrated current sense and timing circuitry. When a solenoid plunger moves, coil inductance shifts measurably; the device detects this shift and reports it via STATUS register bits or STAT_ pin output - enabling contactless verification of mechanical actuation without external sensors.
What protection features are integrated into the MAX22217ATJY+?
The MAX22217ATJY+ 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, ensuring fail-safe behavior even during host MCU reset or communication failure.
Can the MAX22217ATJY+ drive bridge-tied load (BTL) configurations?
Yes, the MAX22217ATJY+ supports BTL operation by configuring two adjacent half-bridges (e.g., OUT1/OUT2) as complementary outputs - enabling H-bridge motor control with bidirectional torque and regenerative braking. The datasheet provides explicit timing diagrams and register settings for BTL mode, including dead-time control to prevent shoot-through.
