Key Features
- Dual reinforced galvanic isolation channels rated up to 5 kVrms, providing safe signal crossing in high-voltage motor drives and inverters
- Sub-100 ns propagation delay per isolated comparator channel enables fast fault detection and protection response in power electronics
- Open-drain outputs on both channels allow wired-OR fault aggregation from multiple protection signals with a single pull-up resistor
Applications
AMC23C14 is used in gate driver fault feedback paths for motor inverters and switched-mode power supplies where overcurrent or overvoltage signals must cross a reinforced isolation barrier within nanoseconds. Its dual-channel design allows simultaneous monitoring of two protection signals such as IGBT desaturation and DC bus overvoltage. The compact small outline package integrates into dense power module layouts.

Frequently Asked Questions
What isolation voltage rating does the AMC23C14 support for safe operation in high-voltage systems?
The AMC23C14 supports reinforced galvanic isolation rated up to 5 kVrms, making it suitable for use in motor drive inverters, solar inverters, and industrial power supplies where the high-voltage power stage must be safely separated from the low-voltage control logic by at least 2 isolation channels.
How quickly does AMC23C14 respond to a fault signal crossing its isolation barrier?
AMC23C14 achieves a propagation delay under 100 ns per isolated comparator channel, which is fast enough to trigger gate driver shutdown before IGBT or MOSFET devices enter destructive overcurrent conditions in a typical motor control or power conversion circuit operating at switching frequencies up to several hundred kHz.
How does the dual-channel architecture of AMC23C14 benefit multi-point fault monitoring designs?
With 2 independent isolated comparator channels in a single package, AMC23C14 allows simultaneous monitoring of 2 separate fault signals—such as IGBT desaturation detection and DC bus overvoltage—across the same isolation barrier, saving board space compared to using two single-channel isolated comparator ICs and reducing system BOM cost.
What output type does AMC23C14 use, and how does this simplify fault signal aggregation?
AMC23C14 uses open-drain outputs on both isolated comparator channels, enabling a simple wired-OR connection where multiple fault outputs share a single pull-up resistor. This means a microcontroller or gate driver can detect any one of several fault conditions on a single GPIO input without requiring additional combinatorial logic, streamlining protection circuit design.
