Product details
Overview
AMC23C10DWVR from Texas Instruments is a reinforced isolated comparator designed for zero-crossing detection of high-voltage AC signals in galvanically separated systems. It features dual independent outputs (open-drain and push-pull), ±6 mV trip threshold error, 230 ns typical propagation delay, and operates across –40°C to +125°C with 3 V–27 V high-side and 2.7 V–5.5 V low-side supplies.
For engineers reviewing the AMC23C10DWVR datasheet, AMC23C10DWVR pinout, AMC23C10DWVR application, or AMC23C10DWVR equivalent, this page delivers verified isolation parameters, dual-output timing behavior, CMTI performance (≥75 V/ns), safety certifications (VDE 0884-17, UL1577), and real-world zero-crossing use cases in solid-state relays and DC/DC converters.
Technical Context
The AMC23C10DWVR implements SiO₂-based reinforced capacitive isolation with on-off keying (OOK) modulation to transmit comparator states across the barrier. Its functional block integrates an LDO regulator on the high-voltage side and separate logic domains for INP/INN analog inputs and OUT1/OUT2 digital outputs.
It supports simultaneous operation of both outputs with built-in 25 mV hysteresis centered at VINN, and includes undervoltage lockout (VDD1UV = 3 V, VDD2UV = 2.7 V), fault detection delay (100 µs), and high-side blanking (200 µs) to ensure robust power-up sequencing in industrial power monitoring.
Key Specifications

| Propagation Delay | 230 ns typ (both outputs, 50 mV overdrive, CL = 15 pF) - enables sub-microsecond zero-crossing response |
| Common-Mode Transient Immunity | ≥100 V/ns (push-pull), ≥75 V/ns (open-drain) - ensures reliable operation in noisy motor drives and inverters |
| Supply Voltage Ranges | High-side: 3 V–27 V (integrated LDO); low-side: 2.7 V–5.5 V - supports wide-input auxiliary supplies and 3.3 V/5 V controllers |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VDD1 | High-side power supply | Input to integrated LDO; powers internal comparator and isolation TX; accepts 3 V–27 V |
| 2 - INP | Noninverting analog input | Primary signal input for zero-crossing detection; supports –1 V to 4 V range relative to GND1 |
| 3 - INN | Inverting analog input | Reference input; typically tied to GND1; defines trip point center with ±12.5 mV hysteresis margin |
| 4 - GND1 | High-side ground | Return path for high-voltage side; galvanically isolated from GND2 |
| 5 - GND2 | Low-side ground | Return path for low-voltage logic side; isolated reference for OUT1/OUT2 |
| 6 - OUT1 | Open-drain output | Active-low output requiring external pullup; Hi-Z when inactive; clamped ≤500 mV above VDD2 |
| 7 - OUT2 | Push-pull output | Active-high/low output; drives rail-to-rail between GND2 and VDD2 without external components |
| 8 - VDD2 | Low-side power supply | Powers RX, logic, and output buffers; 2.7 V–5.5 V compatible with MCU I/O domains |
Key Features

| Reinforced isolation barrier | SiO₂ dielectric with 15.4 µm DTI and >10¹² Ω insulation resistance ensures >400-year lifetime at 1000 VRMS working voltage |
| Integrated high-side LDO | Eliminates need for external high-voltage regulator; supports direct connection to 24 V bus or rectified AC rails |
| Robust power sequencing | Programmed blanking (200 µs), fault detection (100 µs), and UVLO thresholds prevent false triggering during startup or brownout |

Equivalent & Alternatives
The following parts are listed as comparable options for similar isolated comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AMC1301QDWVRQ1 | Single-ended output only; ±1% gain error; no hysteresis; 100 kSPS delta-sigma modulator output | Requires external MCU ADC and digital filtering; not suitable for direct zero-crossing edge generation | Select AMC1301QDWVRQ1 only when high-precision isolated voltage measurement-not fast edge detection-is required. |
| SI8920BD-IS | Isolated amplifier (not comparator); 100 kV/µs CMTI; 1.5 V/V gain; no internal hysteresis or dual outputs | Needs external comparator and level-shifting circuitry to replicate AMC23C10DWVR's zero-crossing function | Choose SI8920BD-IS only if system already includes precision analog signal conditioning and requires isolated voltage scaling. |

FAQ
What is the maximum working voltage supported by the AMC23C10DWVR isolation barrier?
The AMC23C10DWVR supports a maximum rated isolation working voltage (VIOWM) of 1000 VRMS (AC) and 1410 VDC, certified per DIN EN IEC 60747-17 (VDE 0884-17) and UL1577. Its reinforced barrier is rated for continuous operation up to 1 kVRMS, making it suitable for 600 VAC mains-connected equipment and industrial motor drives.
Can the AMC23C10DWVR operate with a 24 V high-side supply and 3.3 V low-side supply simultaneously?
Yes - the AMC23C10DWVR is fully specified for high-side supply (VDD1) from 3 V to 27 V and low-side supply (VDD2) from 2.7 V to 5.5 V. At VDD1 = 24 V and VDD2 = 3.3 V, it maintains ±6 mV trip threshold error, 230 ns propagation delay, and meets all CMTI and safety specifications across –40°C to +125°C.
How does the dual-output architecture of the AMC23C10DWVR improve system design flexibility?
The AMC23C10DWVR provides both open-drain (OUT1) and push-pull (OUT2) outputs on the same die. This allows direct interface to legacy 5 V logic (via pullup on OUT1) and modern 3.3 V MCUs (via rail-to-rail OUT2), eliminates external buffer ICs, and enables redundancy or differential signaling in safety-critical applications without additional isolation components.
Does the AMC23C10DWVR require external components for basic zero-crossing operation?
No - the AMC23C10DWVR integrates an LDO on the high-voltage side and requires only two external decoupling capacitors (recommended: 100 nF ceramic on VDD1 and VDD2). For OUT1 (open-drain), a pullup resistor is needed; for OUT2 (push-pull), no external components are required. No external hysteresis or reference circuitry is necessary due to its internal 25 mV hysteresis and GND1-referenced INN input.
What safety certifications apply to the AMC23C10DWVR and how are they validated?
The AMC23C10DWVR is certified to DIN EN IEC 60747-17 (VDE 0884-17) for reinforced isolation (7000 VPK) and UL1577 (5000 VRMS, 1 minute). These certifications are validated via production-tested impulse voltage (7700 VPK), surge testing (10,000 VPK in oil), and partial discharge screening (<5 pC), ensuring compliance for use in safety-critical industrial and building automation systems.
