programmable DC arc detect reference solution. The RD-195 is designed for deployment in automobile and aircraft battery management systems, industrial factory equipment, and photovoltaic units and offers protection against the catastrophic damage that can result from arc faults. Designers can program the RD-195 to optimize the balance between arc-detection accuracy and false detection prevention to meet their system needs. The RD-195 is accompanied by a software application tool that enables alteration of threshold detection parameters.
The RD-196 is fully programmable. The arc detection threshold parameters can be configured using the accompanying software tool so that the system always detects valid arcs, while minimizing nuisance tripping. It also detects different types of arcs, including series, parallel and ground arcs. In order to achieve the reliability expected in safety-critical environments, the device is designed to operate in noisy environments with RF interference. All signal chain components in the solution operate across the full industrial temperature range of -40 degrees C to +85 degrees C.
The typical response time of the solution is less than 100 ms, which allows the system controller to take quick action, mitigating the consequences of fires caused by arcing.
The RD-195 is certified per the Underwriters Laboratories UL1699B standard, and is listed as a recognized device under UL1998. This helps ease and speed designers' time to market with a UL-certified product. It is also compliant with the NEC690.11 solar power safety requirements.
The RD-195 evaluation module (EVM) enables designers to evaluate the RD-195 for a variety of applications. The EVM includes TI's C2000™ Piccolo TMS320F28033 32-bit microcontroller with C28x core and control law accelerator (CLA), one SM73201 16-bit analog-to-digital converter (ADC), three SM73307 dual-channel precision operational amplifiers (op amps), and one SM73308 low noise, rail-to-rail output op amp. Also included are bill of materials, schematic, board layout files, software application tool, firmware licensing agreement, arc detect code with UL1998 models, and application note.
