Maxim’s total mark products have already released chip group MAXQ3108 and DS8102 of the innate expenses which have reduced a polyphase energy rice. Together, 3 electric current mutual inductors of high expenses that MAXQ3108 and DS8102 replace together with 3 low cost go through transition and rescue expenses and space.

DS8102 include with can programme, reap, order triangle modulating device to 32 x two high-accuracy 2 togethering. The production of the modulating device is translated into the code and become single bit flowing and enabling isolating and reducing with the commissure data to the minimum cost. The data processing quilt is in MAXQ3108, accept bit of 3 DS8102 output to flow in pair central microcontroller, most data of and destroy then decipher produce crude ADC sample cross in wide dynamic ranges. Combine DSP of computing capability, ADC sample is packed into MAXQ3108, energy, power factor, RMS voltage and electric current parameter require a multi-functional ammeter.

Chip group MAXQ3108 and DS8102 reduces the total systematic expenses and hands over the high performance and flexibility for polyphase ammeter so. DSP of MAXQ3108 can also programme, made in the segregation among physical signal and DAQ instrument by the place required and suitable for the chip group employed in many kinds of industrial data collection. Consult and design and suitable for help.

Pair is central MAXQ3108 includes two 16 RISC processor. Pack 64 Kbyte and glimmer and plan memory, 2 Kbyte data SRAM and (VBAT) of what the 16 bytes battery is supported in user’s core Data SRAM. Characteristic digital trimmable real clock and Societe de Placements Interationaux, I²C, pairs of USART port. MAXQ3108 includes the multiplier of the hardware too, decoder and filter and 10 MHz FLL of 3 cubic sincs of 3 Manchester input on 32 kHz.

Meanwhile, DSP core includes 8 Kbytes and can put users’ SRAM code memory, a Kbyte data SRAM and hardware multiplier. If DSP processor deformity, DSP code memory may be used for entering and taking shape as the memory of the data by user’s core. User’s core can be exposed to 10 Kbyte of the memory of the data in this structure. ADC sample (from decimators) Can be applicable to DSP core or user’s core.

DS8102 combines the the sum of the triangles of the second order of 2 modulation device and harvest that can programme together until 32 x. It packs the encoder of Manchester too, internal 8 MHz oscillator and inside consult.

Increase the flexibility
DS8102 modulating device and encoder and MAXQ3108 microcontroller are that polyphase energy rice of today form a unique settlement to isolate and count with commissure According to challenge method. The rice of a three phases uses 3 DS8102s and a MAXQ3108. Every DS8102 floats at one’s own stages that it is measuring. One DS8102 input, change high frequency then pass one low-cost condenser connect to bit of figure of MAXQ3108 flow at present voltage. MAXQ3108 connects to them and accepts one bit of one that floweds of digital data to isolate from every one from 3 DS8102s, but DC exchanged. Because of every DS8102 that is isolated from other stages and from MAXQ3108, can use a shunt resistor for its current feeling at each stage. The expensive electric current mutual inductor is dispelled so, the innate expenses are reduced notably.

Have another advantage to this solution: Data commissure now figure, has not crossed any simulation to input the faithful losses of the range in agony.

MAXQ3108 in 28 TSSOP and DS8102 packaging of safety pin in 16 TSSOP of safety pin. Two pieces of apparatus are operated above - 40°C to +85°C temperature range. The price is 2.43 dollars of MAXQ3108 and DS8102 (1, 000 rise, cheats U.S.A.) 1.17 U.S. dollar .
