Texas Instruments SN6501DBV | Demoboard TIDA-00420
Digitally Isolated 2-Channel, Wide DC Binary Input Module Reference Design
Overview
| Topology | Flyback Converter |
| Input voltage | 3.3 V |
| Switching frequency | 3700-6300 kHz |
| IC revision | A |
Description
This reference design enables translation of high DC voltage inputs upto 300VDC into binary logic level voltages that a typical electronic circuit can handle. This solution is very flexible, not only handling input voltages from 18 to 300VDC but also allowing programmable switching thresholds to set binary levels. In addition, this solution enables < ± 3.0% (± 1V measured value step size) error in voltage detection coupled with reliable isolation > 2kV RMS.
Features
Remark: BOM is added with main pdf.High accuracy voltage measurement capability (< ±3% error)Flexible solution handling input voltages from 18V to 300VDCMCU enables programmable switching thresholdsExcellent long term reliability with digital isolation includedProvides option for wetting current controlOutput can be either I2C or digital output
Typical applications
- Remote Terminal Unit
- Remote I/O
- FTU/DTU/FRTU
- Bay Controller
- Circuit Breaker Digital Input Module
- Power Quality Analyzer
- Multifunction Protection Relays
- Merging Unit
