EM78P142 - 8-Bit Microprocessor with OTP ROM

Description
Clare and IXYS have combined to bring OptoMOS® technology, reliability and compact size to a new family of High Power Solid State Relays. As part of this new family, the CPC1786 single pole normally open (1-Form-A) DC Solid State Relay employs optically coupled MOSFET technology to provide 2500Vrms of input to output isolation.
The output is constructed with an efficient MOSFET switch and photovoltaic die that uses Clare’s patented OptoMOS architecture while the input GaAlAs infrared LED provides the optically coupled control. The combination of low on-resistance and high load current handling capability makes this relay suitable for a variety of high-performance DC switching applications.
The unique i4-PAC package pioneered by IXYS allows solid state relays to achieve the highest load current and power ratings. This package features an IXYS unique process where the silicon chips are soft soldered onto the Direct Copper Bond (DCB) substrate instead of the usual copper leadframe. The DCB ceramic, the same substrate used in high power modules, not only provides 2500Vrms isolation but also very low thermal resistance (0.35°C/W).

Features
*100% Solid State
*Compact i4-PAC™ Power Package
*Low Thermal Resistance (0.35°C/W)
*1.75ADC Load Current with 5ºC/W Heat Sink
*Electrically Non-conductive Thermal Pad for Heat Sink Applications
*No Moving Parts
*Low Drive Power Requirements
*Arc-Free With No Snubbing Circuits
*2500Vrms Input/Output Isolation
*No EMI/RFI Generation
*Machine Insertable, Wave Solderable

Applications
*Industrial Controls
*Motor Control
*Robotics
*Medical Equipment—Patient/Equipment Isolation
*Instrumentation
*Multiplexers
*Data Acquisition
*Electronic Switching
*I/O Subsystems
*Meters (Watt-Hour, Water, Gas)
*Transportation Equipment
*Aerospace/Defense

CPC1786 - i4-PAC™ DC Power Relay

Description
The CS5466 is a low cost power meter solution combining two ΔΣ Analog-to-Digital Converters (ADC)’s, an energy-to-frequency converter, and energy pulse outputs on a single chip. It is designed to accurately measure and calculate energy for single phase 2- or 3- wire power metering applications with minimal external components.
Low frequency energy outputs, E1 and E2, supply average real power and can be used to drive a stepper motor or a mechanical counter; the high frequency energy output FOUT can be used for calibration; and NEG indicates negative power.
The CS5466 has configuration pins which allow for direct configuration of pulse output frequency, current channel input range, and high pass filter enable option. The CS5466 also has a power-on reset function which holds the part in reset until the supply reaches an operable level.

Features
*Single Chip; Power Measurement Solution
*Energy Data Linearity: ±0.1% of Reading over 1000:1 Dynamic Range
*On-Chip functions: Measures Energy and Performs Energy-to-Pulse Conversions
*Meets Accuracy Spec for IEC 687/1036
*High Pass Filter Option
*Four Input Ranges for Current Channel
*On-Chip 2.5 V Reference (25 ppm/°C typ)
*Pulse Outputs for Stepper Motor or Mechanical Counter
*On-Chip Energy Direction Indicator
*Ground Referenced Input Signals with Single Supply
*High Frequency Output for Calibration
*On-Chip Power-on Reset
*Power Supply Configurations: VA+ = +5 V; AGND = 0 V; VD+ = +3.3 V to 5 V
