STPM13A

STPM13A
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
