Reference Designs related to LMV551

  • Signal Processing Subsystem and Current Input Based Self Power for Breaker Applications (ACB/MCCB)
    THe TIDA-00498 reference design features signal processing front-end and self-power block for electronic trip unit (ETU) used in circuit breakers.  A FRAM based micro-controller is used for processing current inputs from signal conditioning amplifiers for 3-phase: neutral and ground current. Two gains are used to extend the range for phase current measurement.This reference design can also self-power using rectified current input. TIDA-00498 is desiged for fast and repeatable tripping (within 30mS) for wide current and temperature range.
  • TIDEP0015 电容式触摸屏显示器参考设计
    Capacitive touchscreen displays generally provide a higher quality and better user experience than traditional resistive touchscreen displays. This reference design shows how to interface a capacitive touchscreen display to the Sitara AM437x processors. The display has an integrated touchscreen c
  • TIDA-01377 使用电感式传感的案例篡改检测参考设计
    智能仪表的实体外壳是防止篡改的第一道防线。智能仪表设计必须包含某种可检测仪表外壳何时被打开的方法,以便提醒服务提供商可能受到了篡改攻击。此参考设计采用了一种适用于此类攻击的低功耗检测新方法,借助小型感应传感器即可准确可靠地确定仪表外壳是否已打开。这种新的解决方案消除了随着时间推移可能会磨损的机械组件,从而提高了系统可靠性。该系统适用于智能电表,但相关设计技术也可应用于水表、燃气表和热量计。
  • EMC Compliant: Group Isolated: 2-Channel Binary Input Module for Wide AC/DC Input Reference Design
    This reference design showcases a cost-optimized architecture that improves resolution of a binary-input module. A microcontroller unit (MCU) is shared between two-input channels (group isolation) to minimize the cost per channel. Wide-input range is covered using an amplifier with gain and MCU-integrated 10-bit analog-to-digital converter (ADC) to measure within ±3% accuracy. This architecture eliminates the need for multiple hardware versions based on input voltage range as is the case with an opto-coupler based topology. A digital isolator is used to communicate the ADC code or the root-mean-square estimate of the input to the host processor. The design is tested for ESD: EFT and surge as per IEC61000-4 Level 4.
