Product details
Overview
AMC23C15QDWVRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive dual isolated window comparator with reinforced galvanic isolation (7000VPK per VDE 0884-17), ±5mV to ±300mV adjustable threshold for comparator 1, ±60mV fixed threshold for comparator 2, and 280ns typical propagation delay - used for overcurrent detection in motor drives and solar inverters.
For engineers reviewing the AMC23C15QDWVRQ1 datasheet, AMC23C15QDWVRQ1 pinout, AMC23C15QDWVRQ1 application, or AMC23C15QDWVRQ1 equivalent, key selection considerations include its dual-window architecture, high CMTI (15V/ns min), open-drain outputs, 3V–27V high-side supply range, and support for both window-comparator and positive-only-comparator modes via REF pin voltage control.
Technical Context
The AMC23C15QDWVRQ1 implements two independent isolated comparators across a reinforced dielectric barrier: one with user-adjustable symmetric thresholds (±VREF) and one with fixed ±60mV thresholds. Its REF pin sources a precision 100μA (±1%) current to set trip points via external resistor, enabling accurate low-voltage sensing down to ±5mV.
It supports mode switching: when REF > 550mV, it disables negative comparators (Cmp1/Cmp3) and operates as two positive-only comparators (Cmp0/Cmp2) with thresholds of VREF and 60mV respectively - ideal for unidirectional supply monitoring. Propagation delay remains consistent at 280ns (typ) across both modes and full temperature range (–40°C to +125°C).

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-channel reinforced isolated amplifier (not comparator); outputs analog voltage, not digital flag | Requires external comparator/MCU ADC; lacks built-in window logic and dual outputs | Choose when analog isolation with programmable gain is needed instead of direct digital fault signaling |
| SI8920BD-IS | Isolated comparator with 100ns propagation delay but no adjustable threshold; fixed 50mV window | No REF pin or threshold programming; limited to fixed-sensitivity detection | Choose when ultra-fast response is prioritized over threshold flexibility and automotive qualification is not required |
Compared with AMC1301QDWVRQ1 and SI8920BD-IS, the AMC23C15QDWVRQ1 uniquely integrates dual isolated window comparators with user-adjustable thresholds, AEC-Q100 Grade 1 qualification, and automotive-grade reinforced isolation - making it the only solution that delivers both programmable sensitivity and functional safety compliance in a single 8-pin SOIC.

FAQ
What is the maximum adjustable threshold range for window comparator 1 in the AMC23C15QDWVRQ1?
The AMC23C15QDWVRQ1 supports an adjustable threshold range of ±5mV to ±300mV for window comparator 1, set by connecting a resistor between the REF pin and GND1. The internal 100μA ±1% current source ensures precise scaling, and the device remains functional even at 5mV, though threshold accuracy degrades slightly due to offset errors at very low voltages.
How does the AMC23C15QDWVRQ1 switch between window-comparator mode and positive-comparator-only mode?
The AMC23C15QDWVRQ1 switches modes based on the voltage applied to the REF pin: when REF rises above 550mV (with 50mV hysteresis), it disables Cmp1 and Cmp3 and activates Cmp0 (trip at VREF) and Cmp2 (trip at 60mV). This allows the AMC23C15QDWVRQ1 to monitor unidirectional supplies like battery voltage or DC bus without negative excursion detection.
What isolation certifications does the AMC23C15QDWVRQ1 hold, and what do they enable?
The AMC23C15QDWVRQ1 is certified to DIN EN IEC 60747-17 (VDE 0884-17) for 7000VPK reinforced isolation and UL1577 for 5000VRMS withstand voltage. These certifications validate its use in ASIL-B automotive systems and industrial equipment where galvanic separation between high-voltage power stages and low-voltage control logic is mandatory for safety and reliability.
Can the AMC23C15QDWVRQ1 be used with a 24V high-side supply and 3.3V low-side MCU?
Yes - the AMC23C15QDWVRQ1 supports high-side supply (VDD1) from 3V to 27V and low-side supply (VDD2) from 2.7V to 5.5V. It operates correctly with 24V on VDD1 and 3.3V on VDD2, making it ideal for automotive 24V systems interfacing with standard 3.3V microcontrollers, with no level-shifting required on the output side.
What is the purpose of the 100nF capacitor recommended on the REF pin of the AMC23C15QDWVRQ1?
The 100nF capacitor on the REF pin of the AMC23C15QDWVRQ1 filters high-frequency noise on the reference current path, improving transient immunity during fast dv/dt events. Placed close to the pin, it stabilizes the 100μA current source and reduces threshold jitter - directly enhancing the repeatability and accuracy of fault detection in noisy power-conversion environments where the AMC23C15QDWVRQ1 is deployed.
