Product details
Overview
MAX22207ATC+T from Analog Devices is a 36V, 3.5A peak full-bridge brushed DC motor driver with integrated non-dissipative current sensing (ICS), current drive regulation (CDR), and open-drain CDR monitor output (CDROUT). It delivers 2A RMS continuous current on a JEDEC 4-layer board at 25°C ambient, features 0.3Ω typical total RDS(ON), and operates across –40°C to +125°C for industrial motion control in compact spaces.
For engineers reviewing the MAX22207ATC+T datasheet, MAX22207ATC+T pinout, MAX22207ATC+T application, or MAX22207ATC+T equivalent, this page provides verified functional identity, validated pin roles, confirmed thermal and current specifications, real-world use-case mapping, and two technically documented alternative parts - all derived from Analog Devices' official MAX22207 datasheet Rev 2 (Jan 2022).
Technical Context
The MAX22207 implements a single-channel H-bridge using low-RDS(ON) N-channel MOSFETs with integrated charge pump, supporting forward/reverse/brake/coast states via dual PWM inputs (IN1/IN2). Its closed-loop current drive regulation (CDR) activates when motor current exceeds ITRIP, forcing fixed 20μs slow-decay off-time and asserting CDROUT low.
Current sensing occurs exclusively during energizing (forward/reverse) and brake (slow decay) phases via sense-FET architecture on both low-side FETs - delivering a scaled replica (KISEN = 5000 A/A) to ISEN pin. CDROUT is an open-drain output requiring external pullup, active only during CDR activation, and not present in MAX22201/MAX22202 variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | VM = 3V to 36V - supports wide-input industrial and battery-powered systems without external regulators. |
| Peak Output Current | 3.5A - limited by overcurrent protection (OCP); defined for short transients, not continuous operation. |
| RMS Output Current | 2A - thermally limited on JEDEC 4-layer PCB at 25°C ambient; actual max depends on layout and cooling. |
| Total RDS(ON) | 0.3Ω (typ) - high-efficiency switching reduces conduction loss and self-heating in space-constrained designs. |
| Current Sense Accuracy | ±3% (DKISEN1) at 0.8–2A - enables precise torque feedback for closed-loop motor control algorithms. |
| CDR Off-Time (tOFF) | 20μs (typ) - fixed internal value; triggers slow-decay mode to limit inrush/stall current without external timing components. |
| Operating Temperature | –40°C to +125°C - qualified for automotive under-hood and industrial embedded environments. |
Pinout & Package
MAX22207ATC+T is housed in a thermally enhanced TDFN-EP package (3mm × 3mm, 12-pin), with exposed paddle (GNDP) soldered to PCB ground plane for optimal thermal dissipation (θJA = 41°C/W on 4-layer board).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 ILIM | Configurable current limit analog input | Connect resistor to GND to set ITRIP per KILIM = 50 kV; enables precise stall/inrush current control. |
| 2 - | Not connected (NC) on MAX22207 | No function - pin 2 is unused; differs from MAX22201 (ROFF) and MAX22202 (MODE). |
| 3 OUT2 | H-bridge output terminal 2 | Drives one side of brushed DC motor winding; complements OUT1 for bidirectional control. |
| 4 IN2 | PWM logic input 2 | Controls bridge state with IN1: 0/1 = reverse, 1/0 = forward, 1/1 = brake, 0/0 = coast/sleep after 2.2ms. |
| 5 IN1 | PWM logic input 1 | Primary control input paired with IN2; both low >2.2ms enters 6.5μA sleep mode. |
| 6 GNDP | Power ground (exposed pad) | Must be soldered to large PCB ground plane - critical for thermal performance and EMI reduction. |
| 7 VM | Main power supply input (3–36V) | Bypass with 1μF ceramic + 47μF bulk capacitor; powers H-bridge, gate drivers, and internal LDO. |
| 8 ISEN | Current sense monitor output | Sources IOUT/5000 A - connect resistor to GND for voltage feedback to MCU ADC (e.g., 2.5kΩ → 1V at 2A). |
| 9 OUT1 | H-bridge output terminal 1 | Drives opposite side of motor winding; forms complete full-bridge path with OUT2. |
| 10 FAULT | Open-drain fault indicator | Active-low signal asserted on OCP, UVLO, or TSD; requires external pullup to VM or V18. |
| 11 V18 | Internal 1.8V LDO output | Supplies logic-level circuitry; 20mA max; bypass with 1μF ceramic; UVLO threshold 1.65V. |
| 12 CDROUT | CDR monitor open-drain output | Asserts low only when CDR is active - unique to MAX22207; enables real-time regulation status monitoring. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated current sensing (ICS) | Eliminates external shunt resistors - saves PCB area, avoids 1–2W power loss, and improves system efficiency. |
| Current drive regulation (CDR) | Automatically limits peak current during startup/stall without software intervention - enhances reliability and reduces supply ripple. |
| CDROUT pin | Dedicated hardware flag signaling CDR activation - enables synchronized firmware response (e.g., throttle adjustment or fault logging). |
| TDFN12 3×3mm package | 0.75mm profile with exposed thermal pad - supports ultra-compact motor control modules in drones, medical pumps, and robotics. |
| Full protection suite | OCP (3.5A threshold), UVLO (2.85V), TSD (165°C), and 8kV HBM ESD on OUT pins - ensures robust operation in noisy industrial environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar brushed DC motor driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX22201ATC+T | Lacks CDROUT; includes ROFF pin for user-configurable tOFF (10–80μs); same pinout except pin 2 = ROFF instead of NC. | Preferred when adaptive decay timing is needed for variable motor inductance or dynamic load profiles. | Select MAX22201ATC+T if tOFF tuning is required; otherwise MAX22207ATC+T simplifies design with fixed 20μs regulation timing. |
| DRV8876NPRGER | TI part: 36V, 3.6A peak, but uses external current sense resistor; no integrated ICS or CDROUT; 16-pin QFN vs. 12-pin TDFN. | Suitable for cost-sensitive designs where PCB area is less constrained and external sensing is acceptable. | Choose DRV8876NPRGER only if legacy design reuse or dual sourcing justifies added BOM cost and layout area for shunt resistor and filtering. |
Compared with MAX22201ATC+T, MAX22207ATC+T trades tOFF configurability for dedicated CDR status visibility - enabling deterministic firmware response to regulation events. Against DRV8876NPRGER, MAX22207ATC+T reduces component count, eliminates sense-resistor power loss, and shrinks footprint by 25%, at the cost of vendor-specific feature integration.

FAQ
What is the maximum continuous current the MAX22207ATC+T can deliver?
The MAX22207ATC+T delivers up to 2A RMS continuously under standard JEDEC 4-layer board conditions at 25°C ambient temperature. This rating assumes adequate PCB copper area for heat dissipation. Real-world current capacity decreases with rising ambient temperature, reduced copper area, or lack of airflow - always verify junction temperature remains below 150°C using θJA = 41°C/W.
How does the CDROUT pin on the MAX22207ATC+T differ from FAULT?
CDROUT on the MAX22207ATC+T is an open-drain output that asserts low only when the internal current drive regulation (CDR) loop is actively limiting current - indicating normal regulation, not failure. In contrast, FAULT signals hard faults: overcurrent (OCP), undervoltage (UVLO), or thermal shutdown (TSD). CDROUT enables proactive system response (e.g., reducing PWM duty cycle), while FAULT demands immediate shutdown.
Can the MAX22207ATC+T drive a stepper motor?
Yes - the MAX22207ATC+T can drive one phase of a bipolar stepper motor, as explicitly stated in its Applications section. It provides full H-bridge control (forward/reverse/brake) for unidirectional current in one winding. For full 2-phase stepper control, two MAX22207ATC+T devices are required - one per phase - coordinated by an external controller.
What external components are mandatory for basic operation of the MAX22207ATC+T?
Four components are mandatory: (1) 1μF ceramic capacitor from VM to GND, (2) 47μF bulk electrolytic capacitor from VM to GND, (3) 1μF ceramic capacitor from V18 to GND, and (4) a resistor from ILIM to GND to set ITRIP (e.g., 25kΩ for 2A limit). Optional but recommended: pullup resistor on CDROUT and FAULT, and resistor on ISEN for current-to-voltage conversion.
Is the MAX22207ATC+T pin-compatible with MAX22201ATC+T or MAX22202ATC+T?
No - MAX22207ATC+T is not pin-compatible with MAX22201ATC+T or MAX22202ATC+T. While all three share the same TDFN12 package and 12-pin layout, pin functions differ: pin 2 is NC on MAX22207ATC+T but ROFF on MAX22201ATC+T and MODE on MAX22202ATC+T; pin 12 is CDROUT on MAX22207ATC+T but unused on the others. PCB layout must be specific to each variant.
