STPM14A
Single phase energy metering IC with pulsed output and digital calibration, TSSOP20, STM, RoHS


The STPM1x family is designed for effective measurement of active energy in a power line system using a Rogowski Coil, current transformer and shunt sensors. This device is specifically designed to provide all the necessary features to implement a single phase energy meter without any other active component.

Features:

  • Ripple free active energy pulsed output
  • Direct stepper counter drivers
  • Shunt, current transformer, Rogowsky coil sensors
  • Live and neutral monitoring (STPM13/14)
  • Easy and fast digital calibration at only one load point
  • No-load, negative power and tamper indicators
  • Integrated linear VREGs
  • RC (STPM11/13) or crystal oscillator (STPM12/14)
  • Support 50 ÷ 60 Hz - IEC62052-11, IEC62053-2X specification
  • Less than 0.1% error
