Zero drift PGA based Analog Front End Design for Circuit Breakers (ACB/MCCB-ETU)
This reference design is intended for use in molded case circuit breakers (MCCB) electronic trip units. The programmable gain amplifier based design acts as the current monitoring for over-current earth fault relays. Utilizing a zero drift programmable amplifier: this design provides a ±10 % pick-up (A) accuracy and time delay (s) accuracy of 0 to -20%. Additionally: this solution was designed to handle harsh environment conditions by including features such as ambient insensitivity from -10 to 70 ⁰C and high electromagnetic immunity. Finally the analog front end of this design interfaces seemlessly with the TI MSP430 MCU for quicker evaluation and faster time-to-market.
