NCS37014数据手册集成电路（IC）的电源管理-专用规格书PDF

描述 Description

The NCS37014 is a UL943 compliant signal processor for GFCI
applications with self test. The device integrates a flexible power
supply (including a 12 V shunt and two 3.3 V internal series
regulators), differential fault, and grounded−neutral detection circuits.
Self test is monitored at start up and then every 17 minutes.

特性 Features

• Auto monitoring test function required by UL943
• Compliant with UL self test requirements and minimal BOM impact
• Self syncing internal oscillator adjusts to AC mains frequency to guarantee full resolution
• Compatible with global AC power systems
• Typical 575 µA Quiescent Current @ 11 V
• Energy efficient GFCI solution
• Tiered trip times by the level of ground fault
• Increase immunity to noise
• Under voltage detection
• Allow for increased operation at lower AC input voltages

应用 Application

• UL943 compliant GFCI products with self test
• GFCI receptacles
• GFCI circuit breakers
• Portable GFCI products
