Product details
Overview
AD8214WYRMZ-RL from Analog Devices is an automotive-qualified, high-voltage current shunt comparator designed for high-side overcurrent detection in DC systems. It operates from 5 V to 65 V supply, delivers <100 ns input-to-output response, features 10 mV hysteresis and integrated 2.4 V regulator, and is used in motor control, battery protection, and transmission systems.
For engineers reviewing the AD8214WYRMZ-RL datasheet, AD8214WYRMZ-RL pinout, AD8214WYRMZ-RL application, or AD8214WYRMZ-RL equivalent, key selection criteria include high common-mode voltage tolerance (up to 68 V survival), fast propagation delay under overdrive, current-output interface compatibility with ground-referenced logic, and automotive-grade temperature range (−40°C to +125°C).
Technical Context
The AD8214WYRMZ-RL implements a high-side–optimized comparator architecture powered by an internal 2.4 V series regulator referenced to VS, enabling direct operation from battery rails up to 65 V. Its differential inputs accept common-mode voltages from VS − 0.9 V to VS + 0.2 V, allowing sensing across shunts placed on the high side of loads.
It uses a current-output stage (1 mA typical high, 100 nA low) with output compliance up to VS − 2.4 V, and integrates 10 mV hysteresis to suppress noise-induced false triggering during slow current transients near threshold. Input offset is ±3 mV (typ), drift ±10 µV/°C, and dynamic error remains ≤15 mV for input ramp rates ≤100 mV/µs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 5 V to 65 V operating; 0 V to 68 V survival - supports 12 V/24 V/48 V automotive and industrial battery rails with margin. |
| Input-to-Output Response | <100 ns typical - enables sub-microsecond overcurrent shutdown in motor FETs and solenoid drivers. |
| Hysteresis | 5 mV to 12 mV (typ 10 mV) - prevents oscillation during noisy or slowly decaying fault currents. |
| Regulator Output | 2.43 V ±5% (−40°C to +125°C) - stable reference for external resistor-divider threshold setting. |
| Input Offset Voltage | ±3 mV (25°C), ±8 mV (full temp) - defines minimum detectable shunt voltage difference at threshold. |
| Operating Temperature | −40°C to +125°C - qualified per AEC-Q100 for under-hood and powertrain applications. |
| Package | 8-lead MSOP (RM-8), 3.0 mm × 3.0 mm - compact footprint compatible with automated SMT assembly. |
Pinout & Package
AD8214WYRMZ-RL is housed in an 8-lead MSOP (RM-8) package compliant with JEDEC MO-187-AA, with 0.65 mm pitch and coplanarity ≤0.10 mm. Pin 1 is marked with a dot; pins 4 and 7 are no-connect (NC) and must remain unconnected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VS) | Positive Supply Input | Connects directly to high-side rail (5 V–65 V); powers internal circuitry and regulator. |
| 2 (+IN) | Noninverting Input | Accepts user-defined threshold voltage via external R1/R2 divider referenced to VREG. |
| 3 (VREG) | Regulator Output | 2.4 V output referenced to VS; supplies internal electronics and sets comparator reference. |
| 4 (NC) | No Connect | Internally unconnected; must be left floating or grounded (not recommended). |
| 5 (OUT) | Current Output | Sinks ~100 nA (low) or sources ~1 mA (high); drives ground-referenced load resistor for logic-level output. |
| 6 (GND) | Ground Reference | Internal ground node; connects to system ground - not tied to VS or shunt return. |
| 7 (NC) | No Connect | Internally unconnected; must be left floating. |
| 8 (–IN) | Inverting Input | Connected to shunt resistor's high-side terminal; senses current-induced voltage drop relative to +IN. |
Key Features
| Feature | Design Value |
|---|---|
| High-side–optimized architecture | Enables direct connection to battery or bus rail without level-shifting, reducing BOM count and layout complexity. |
| Integrated 2.4 V regulator | Provides stable, temperature-compensated reference for precise threshold setting via external resistors - eliminates need for external reference IC. |
| Current-output interface | Delivers robust 1 mA high-state drive into ground-referenced loads, simplifying interfacing with microcontrollers, FET drivers, or optocouplers. |
| Automotive qualification | AEC-Q100 Grade 0 qualified (−40°C to +125°C), with controlled manufacturing and reliability reporting - suitable for safety-critical powertrain systems. |
| Built-in hysteresis | 10 mV typical hysteresis reduces susceptibility to EMI and thermal noise near trip point, eliminating need for external RC filtering. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side current shunt comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX40056ATA+T | Fixed 50 mV threshold; no external resistor option; 150 ns response; 5 V to 60 V supply. | Lacks programmable threshold - limited to fixed-current trip points; lower supply max than AD8214WYRMZ-RL. | Select when simplicity and cost outweigh need for adjustable trip voltage and fastest response. |
| INA301A3IDBVR | Voltage-output (not current-output); 1.2 V to 5.5 V supply only; requires external bias; 350 ns response. | Not high-side–capable without external level shift; unsuitable for direct 12 V/24 V rail sensing. | Select only for low-voltage, low-power systems where supply is regulated below 5.5 V and level shifting is acceptable. |
Compared with MAX40056ATA+T and INA301A3IDBVR, AD8214WYRMZ-RL uniquely combines automotive qualification, programmable threshold via integrated 2.4 V regulator, sub-100 ns response, and true high-side operation up to 65 V - making it the only choice for demanding powertrain overcurrent protection where timing, flexibility, and ruggedness are jointly required.

FAQ
What is the maximum common-mode voltage the AD8214WYRMZ-RL can withstand?
The AD8214WYRMZ-RL supports a continuous input common-mode voltage range of VS − 0.9 V to VS + 0.2 V, with absolute maximum survival rating of 68 V. This allows direct connection to 12 V, 24 V, and 48 V automotive battery rails while tolerating load-dump transients up to 68 V without damage or latch-up.
How does the AD8214WYRMZ-RL set its current threshold voltage?
The AD8214WYRMZ-RL uses its integrated 2.4 V regulator (pin 3, VREG) to power an external resistor divider between VREG and GND. The junction of R1 and R2 connects to +IN (pin 2), establishing a user-selectable threshold - for example, 75 mV with R1 = 6.25 kΩ and R2 = 193.75 kΩ. The AD8214WYRMZ-RL compares the shunt voltage at –IN (pin 8) against this threshold.
Can the AD8214WYRMZ-RL drive a standard logic input directly?
Yes - the AD8214WYRMZ-RL's current-output stage (1 mA high, 100 nA low) easily drives a ground-referenced pull-up resistor to generate clean 0 V / 3.3 V or 0 V / 5 V logic levels. With a 3.3 kΩ load resistor, the AD8214WYRMZ-RL delivers ~3.3 V high and ~0 V low, compatible with most MCU GPIOs and FET drivers without additional buffering.
Is the AD8214WYRMZ-RL pin-compatible with other variants in the AD8214 family?
Yes - all AD8214 variants including AD8214ARMZ, AD8214WYRMZ-RL, and AD8214WYRMZ-R7 share identical 8-lead MSOP (RM-8) pinout, electrical characteristics, and functional behavior. The "W" suffix denotes automotive qualification, "Y" branding indicates automotive traceability, and "-RL" denotes 13" tape-and-reel packaging - all retain full pin and function compatibility with AD8214WYRMZ-RL.
What is the purpose of the hysteresis in the AD8214WYRMZ-RL?
The AD8214WYRMZ-RL incorporates 10 mV typical hysteresis to prevent output chatter during slow or noisy transitions near the trip threshold. Once triggered high by overcurrent, the AD8214WYRMZ-RL requires the shunt voltage to fall 10 mV below the original trip point before returning low - ensuring stable, noise-immune fault signaling in electrically harsh automotive environments.
