Description

The Internet of Things (IoT) revolution is efficiently connecting applications and instruments, enabling battery powered, wide scale very low power sensor deployment.  New technologies, such as TI’s advanced sensor and low power connectivity devices, are enabling these instruments to be designed as battery powered wireless systems dramatically improving cost, deployment, reliability, performance and complexity.

Enabled by Texas Instruments’ SimpleLink™ ultra-low power wireless micro-controller (MCU) platform, the TIDA-01014 reference design utilizes the TIDA-01012 wireless DMM reference design to demonstrate how the bq27426 can be used to enhance the battery management system’s fuel gauge performance and ultimately optimize consumption. The TIDA-01014 features a wirelessly connected, 4½ Digit, 100kHz true RMS, DMM with Bluetooth Low Energy® (BLE) connectivity, NFC Bluetooth pairing, and an Automatic Wake-Up feature enabled by TI’s CapTIvateTM technology.

Features
  • Wireless MCU enabling Bluetooth low energy (BLE) for IoT wireless
  • Low power design and power management systems
  • Battery discharge monitoring
  • Increased fuel gauge accuracy and resolution
