Texas Instruments AMC23C10DWV

Overview

AMC23C10DWV 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 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 AMC23C10DWV datasheet, AMC23C10DWV pinout, AMC23C10DWV application, or AMC23C10DWV equivalent, this device delivers fast, safety-certified isolation for high-reliability monitoring in solid-state relays, factory automation, building control, and DC/DC converters where precise timing and noise immunity are critical.

Technical Context

The AMC23C10DWV implements SiO₂-based capacitive reinforced isolation with on-off keying (OOK) modulation to transmit comparator states across the barrier. Its dual-output architecture enables flexible interface design: OUT1 provides open-drain logic-level signaling with external pull-up dependency, while OUT2 delivers rail-to-rail push-pull drive without external components.

It integrates a high-side LDO supporting wide input voltage (3 V–27 V), enabling direct connection to HV bus rails. The comparator core includes 25 mV hysteresis centered on INN, with trip thresholds referenced to GND1 and validated over full temperature and supply ranges. CMTI exceeds 75 V/ns (open-drain) and 100 V/ns (push-pull), meeting stringent industrial noise environments.

FAQ

What is the isolation voltage rating of the AMC23C10DWV?

The AMC23C10DWV is certified for 5000 VRMS isolation (1 minute per UL1577) and 7000 VPK reinforced isolation per DIN EN IEC 60747-17 (VDE 0884-17). Its working voltage is rated at 1000 VRMS AC or 1410 VDC, making it suitable for use in Class I and II mains-connected equipment with proper PCB layout.

Does the AMC23C10DWV require external hysteresis components?

No, the AMC23C10DWV includes 25 mV of internal hysteresis centered on the INN pin. This eliminates the need for external resistors or capacitors to stabilize switching behavior during slow-moving or noisy input signals-critical for reliable zero-crossing detection in AC line monitoring applications.

How does the dual-output architecture of the AMC23C10DWV benefit system design?

The AMC23C10DWV provides both open-drain (OUT1) and push-pull (OUT2) outputs on the same die. This allows designers to interface directly with legacy optocoupler-driven circuits (via OUT1 with pull-up) and modern microcontrollers with CMOS inputs (via OUT2), reducing bill-of-materials and simplifying layout without sacrificing flexibility.

What is the maximum common-mode transient immunity (CMTI) of the AMC23C10DWV?

The AMC23C10DWV achieves ≥100 V/ns CMTI on its push-pull output (OUT2) and ≥75 V/ns on its open-drain output (OUT1), measured with |VINP – VINN| ≥ 25 mV. These values are guaranteed minimums across –40°C to +125°C and ensure robust operation in high-dV/dt environments like motor drives and switch-mode power supplies.

Can the AMC23C10DWV operate with different supply voltages on each side?

Yes-the AMC23C10DWV supports independent supplies: VDD1 (high-side) from 3 V to 27 V and VDD2 (low-side) from 2.7 V to 5.5 V. This decoupling enables direct connection to HV bus rails and compatibility with 3.3 V or 5 V logic domains, eliminating level-shifters and simplifying power architecture.
