What is the "stand-alone type" LSI means?
Stand-alone type LSI is not controlled by microcontroller. It executes monitoring of cell voltage, current, temperature by itself and protects battery systems.
What is the "Analog Front End type" LSI means?
This type LSIs have interface function with batteries and microcontroller. Microcontroller measure battery voltage and current, and this type LSIs are controlled by microcontroller.
What is the maximum ambient temperature that Thermoelectric coolers or assemblies can operate in?
The maximum operating temperature of standard thermoelectric coolers is 80⁰C. For higher temperatures, our HiTemp ETX Series thermoelectric cooler offer cooling for applications with ambient temperatures up to 150°C. For thermoelectric cooler assemblies, the Outdoor Cooler Series has the widest capacity range with an operational capacity from -40°C to +55°C ambient. The SuperCool Series thermoelectric cooler assembly can withstand the highest temperature of 60°C.
What is the maximum cooling capacity you provide?
Our Liquid Cooling Systems have the highest cooling capacity in our standard product portfolio. The largest capacity is our Ambient Cooling Systems with cooling capacities up to 5 kW. Custom solutions have been designed with capacities greater than 40 kW’s. The largest capacity of a thermoelectric cooler assembly is our Outdoor Cooler Series AA-480 and it has a cooling capacity of 480 Watts. The largest capacity of a thermoelectric cooler is the HiTemp ETX Series ETX15-28-F2-5252-TA-RT-W6 and it has a cooling capacity of 322 Watts.

Is the RF SAW filter needed?
Although it is not needed for meeting the standard, we recommend to insert the RF SAW filter because interfering sources may exist near any actual operation band. Related Products: ML7344/ML7406 family, ML7345 family, ML7396 family, ML7404, ML7414
In the A/D converter of the ML62Q1000 series, it is said that it is possible to select whether or not to discharge the sample hold capacitance with the SAINIT bit. What is the standard for using with or without discharge?
With no discharge, the charging and discharging of the sample hold capacitor inside the A/D converter is minimized, and the voltage fluctuation of the terminal becomes small, which is effective for A/D conversion of only one channel. With discharge, the phenomenon that the result of the previous A/D conversion affects the next channel is eliminated, and the degree of influence becomes the same each time, so it is effective when performing A/D conversion for two or more channels. However, even with the above settings, there is a concern that the A/D conversion results may be shifted due to fluctuations in the terminal voltage. In this case, it is necessary to take countermeasures such as extending the A/D sample hold time or reducing the frequency of A/D conversion.

Is it possible to generate a ROM code data file with HTU8, and write to flash ROM to evaluate without acquiring a ROM code number?
Yes. It is possible to generate a ROM code data file with HTU8, and write to flash ROM to evaluate without acquiring a ROM code number. The content itself on the ROM code data file output by HTU8 is not related to a ROM code number.
