Product details
Overview
MAX22216ATJY+ from Analog Devices is a quad 36V smart serial-controlled half-bridge driver IC designed for precision solenoid and DC motor control in industrial automation and automotive electromechanical systems. It delivers up to 3.2A full-scale current per channel, supports voltage/current/mixed drive regulation modes, integrates real-time current sensing and plunger movement detection, and operates across –40°C to +125°C ambient.
For engineers reviewing the MAX22216ATJY+ datasheet, MAX22216ATJY+ pinout, MAX22216ATJY+ application, or MAX22216ATJY+ equivalent, this page provides verified technical context, diagnostic capability details, SPI/OTP configuration options, protection behavior, and validated alternative part guidance for solenoid valve and proportional actuator designs.
Technical Context
The MAX22216ATJY+ implements four independent, programmable half-bridge output stages with integrated high-side and low-side MOSFETs. Each channel supports configurable slew-rate control (100–800 V/µs), dead time (0.1 µs), and selectable current-sense scaling (SNSF[1:0] = "00" to "10") to match load dynamics and EMI requirements.
It features dual regulation architectures: Voltage Drive Regulation (VDR) with internal supply compensation, and Current Drive Regulation (CDR) using closed-loop PI control with user-configurable proportional/integral gains. Diagnostic functions-including inductance measurement, travel time capture, and open-load detection-are implemented via dedicated status registers accessible over SPI.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad half-bridge driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX22217ATJY+ | Lower full-scale current (1A vs. 3.2A), identical pinout and register map; shares OTP/SPI architecture and diagnostic suite | Better suited for low-power proportional valves and micro-motors where thermal headroom is constrained | Select when peak load current ≤1A and board space/layout reuse is critical |
| TLE9201SG | Automotive-qualified (AEC-Q100 Grade 0), 4-channel high-side switch (not half-bridge); no current regulation or DPM diagnostics | Targeted at simpler ON/OFF loads in automotive body electronics; lacks solenoid-specific features like dither or demag | Choose only for cost-sensitive automotive lighting or relay control-no functional replacement for MAX22216ATJY+'s advanced regulation and diagnostics |
Compared with MAX22216ATJY+, MAX22217ATJY+ offers identical functionality at reduced current capability and lower thermal load, while TLE9201SG provides basic high-side switching without regulation or intelligent diagnostics-making it unsuitable for precision solenoid or motor control where closed-loop current accuracy and mechanical state verification are required.

FAQ
What is the maximum continuous output current per channel for the MAX22216ATJY+?
The MAX22216ATJY+ supports up to 3.2A full-scale current per half-bridge channel under specified thermal conditions. Its actual continuous DC current capability is 1.7A at TA = 25°C, derating linearly with junction temperature. This rating assumes proper PCB layout with thermal vias to the exposed pad and adequate copper area per the land pattern number 90-100082. The MAX22216ATJY+ achieves this performance using low-RON MOSFETs (0.17Ω typical HS, 0.17–0.83Ω LS depending on SNSF setting).
Does the MAX22216ATJY+ support both SPI and one-time programmable (OTP) configuration?
Yes, the MAX22216ATJY+ supports dual configuration modes: real-time SPI-based register updates for dynamic control, and factory-programmed OTP registers for stand-alone operation after power-up. OTP programming requires controlled temperature/voltage conditions and is irreversible. Once programmed, OTP settings load automatically at boot, enabling autonomous operation without host MCU intervention-ideal for safety-critical or resource-constrained systems. The MAX22216ATJY+ retains full SPI accessibility even with OTP enabled.
How does the plunger movement detection (DPM) feature work in the MAX22216ATJY+?
The MAX22216ATJY+ implements plunger movement detection (DPM) by analyzing transient coil voltage and current responses during controlled excitation pulses. It measures inductance shifts and reaction time delays to distinguish between mechanical motion and stuck-plunger faults. Results are reported via STATUS register bits and optionally asserted on the STAT_ pin. This capability is validated per IEC 61508 and used in functional safety architectures to confirm actuator integrity-directly supporting diagnostic coverage claims for MAX22216ATJY+ in ISO 13849 PLd systems.
Can the MAX22216ATJY+ drive bridge-tied load (BTL) configurations?
Yes, the MAX22216ATJY+ supports bridge-tied load (BTL) operation by pairing two half-bridges per channel-for example, OUT_A and OUT_B can form a full H-bridge to drive bidirectional DC motors or push-pull solenoids. This mode requires coordinated PWM control via SPI register writes to CNTL bits and enables higher effective voltage swing (up to 2×VM) and improved torque linearity. BTL configuration is explicitly documented in the functional diagrams and register map of the MAX22216ATJY+ datasheet.
What protection features are integrated into the MAX22216ATJY+?
The MAX22216ATJY+ integrates overcurrent protection (OCP) with blanking time (1.45–2.85 µs) and configurable thresholds (1.2–4A), overtemperature protection (OVT) with automatic shutdown at TJ > +150°C, undervoltage lockout (UVLO) on VM (3.75–4.25V), and open-load detection during OFF state. All faults assert the open-drain FAULT pin and set corresponding status bits in the FAULT register. These protections operate independently per channel and are active in both SPI and OTP modes-ensuring robust operation without host supervision. The MAX22216ATJY+ also includes internal charge pump supervision and logic supply monitoring.
