Product details
Overview
The MAX22216ATJY+T from Analog Devices is a quad-channel, serial-controlled 36V smart 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 regulation modes, integrates real-time current sensing, and operates across –40°C to +125°C ambient temperature - enabling robust operation in valve actuation, proportional solenoid control, and brake drive applications.
For engineers reviewing the MAX22216ATJY+T datasheet, MAX22216ATJY+T pinout, MAX22216ATJY+T application, or MAX22216ATJY+T equivalent, this page provides verified technical context on SPI/OTP configuration, diagnostic functions (DPM, inductance measurement), protection architecture (OCP/OVT/UVM), and package-specific thermal performance for TQFN32 (5mm × 5mm) layout integration.
Technical Context
The MAX22216ATJY+T implements four independent, programmable 36V half-bridges with configurable high-side/low-side or bridge-tied load (BTL) topologies. 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 advanced diagnostics including detection of plunger movement (DPM), travel time measurement, open-load detection (OL), and real-time digital current monitoring via SPI. Protection includes overcurrent (OCP), overtemperature (OVT), and undervoltage lockout (UVM), with fault status reported on the dedicated FAULT pin.

Key Features
| Feature | Design Value |
|---|---|
| Programmable CDR/VDR per channel | Enables adaptive control: VDR for stable voltage delivery, CDR for precise current limiting during motor stall or solenoid pull-in |
| Two-level sequencer | Reduces average power by switching between active and low-power "nap" states - extends system energy efficiency in intermittent-duty valves |
| Dither function (DITH) | Applies controlled AC excitation to counteract static friction and hysteresis in proportional solenoids - improves linearity and repeatability |
| Ramp control (RAMP) | Configurable slew-rate (100–800 V/µs) limits EMI and mechanical shock during turn-on/turn-off transitions |
| Fast demagnetization (DC_H2L) | Shortens solenoid release time by actively discharging inductive energy - critical for high-cycle-rate valve timing |
| Integrated current sense | Eliminates external shunt resistors; provides 12-bit digital current readback via SPI for closed-loop tuning and health monitoring |

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 |
|---|---|---|---|
| MAX22217ATJY+T | Lower full-scale current (1A vs. 3.2A); identical pinout, SPI interface, and diagnostic features | Better suited for low-power proportional valves and micro-motors where thermal budget is constrained | Select MAX22217ATJY+T when peak load current ≤1A and board space/thermal design favors lower dissipation |
| TLE9201SG | Single-channel 40V half-bridge; no integrated current sense ADC or DPM diagnostics; requires external shunt and MCU-based control | Targeted at cost-sensitive, non-diagnostic applications like basic relay or fan drivers | Choose TLE9201SG only if diagnostics, multi-channel integration, and SPI configurability are not required |
Compared with MAX22216ATJY+T, the MAX22217ATJY+T offers identical functionality at reduced current capability and thermal footprint, while the TLE9201SG lacks integrated diagnostics and multi-channel coordination - making MAX22216ATJY+T the optimal choice for high-reliability, sensor-rich electromechanical control where channel density and predictive maintenance are critical.

FAQ
What is the maximum continuous current capability per channel of the MAX22216ATJY+T?
The MAX22216ATJY+T supports up to 3.2A full-scale current per half-bridge channel under specified thermal conditions (TA ≤ +70°C, four-layer board). At 25°C ambient, its DC current rating is 1.7A per channel. Actual sustained current depends on PCB copper area, airflow, and VM voltage - thermal derating begins above +70°C at 34.5mW/°C.
Does the MAX22216ATJY+T support standalone operation without an external microcontroller?
Yes, the MAX22216ATJY+T supports standalone operation via one-time programmable (OTP) registers. Configuration settings - including drive mode, current limits, and sequencer behavior - can be factory-programmed into OTP memory and automatically loaded at power-up, eliminating the need for continuous SPI communication.
How does the Detection of Plunger Movement (DPM) function work in the MAX22216ATJY+T?
The MAX22216ATJY+T implements DPM by analyzing real-time voltage and current transients during solenoid energization. It detects characteristic impedance shifts corresponding to plunger motion, enabling verification of mechanical actuation without external sensors. This feature is accessible via SPI register reads and supports both pass/fail reporting and analog waveform capture.
Can the MAX22216ATJY+T drive a bridge-tied load (BTL) configuration?
Yes, the MAX22216ATJY+T supports BTL operation by pairing two half-bridges per channel (e.g., OUT_A/OUT_B for Channel 1). This doubles effective drive voltage across the load, enabling higher torque in DC motor applications or improved force linearity in voice-coil actuators - all configurable via SPI register writes.
What protection features are integrated into the MAX22216ATJY+T?
The MAX22216ATJY+T integrates overcurrent protection (OCP) with blanking time, overtemperature protection (OVT), undervoltage lockout (UVM), open-load detection (OL), and fault reporting via the dedicated FAULT pin. All protections are hardware-asserted and latched until cleared via SPI or power cycle - ensuring fail-safe behavior in mission-critical systems.
