16-channel active cell balancing reference design

16-cell EV/HEV high current active solution using the latest automotive battery management monitor and protector bq76PL455A-Q1. It combines the high level of integration and accuracy of the bq76PL455A-Q1 with a bidirectional DC-DC cell balancer to provide a high-performance battery management solution for high-capacity battery packs. This allows any 16-cell input to be charged or discharged as required at up to 5A, and modules can be stacked up to 1300V.

Open source power meter: with power supply function, dedicated to IoT power consumption measurement

The biggest feature of testing the power consumption of IoT devices is the high dynamic range, a few uA in the sleep state and hundreds of mA in the transmitting state, and it supports dynamic switching of the measurement range. The open source power meter ZS1100A has a dynamic measurement range of 1uA to 1.5A, a resolution of 100nA, and an accuracy of 1% ± 200 nA, which is very good.

XDPL8105 40W Reference Design

The XDPL8105 40W reference design is a digital ground configured LED driver with a universal input of 90-305 V AC, a wide output load range of 16-45VDC and isolated 0-10V dimming based on a CDM10V dimming IC. The power stage uses IPD80R1K4CE, a 900mOhm CoolMOS™ CE power MOSFET. 

Sony's super powerful IoT kit based on its own CXD5602 (open source information)

The biggest highlight of this kit is Sony's own 6-core microcontroller CXD5602, which comes with 1.5MB of general-purpose SRAM, 64KB of backup SRAM, and a main frequency of 156MHz. There is also an M0+ core assist processor for IO control management, which comes with 256KB of general-purpose SRAM. The built-in GNSS receiver supports GPS and GLONASS. Others include 2D graphics acceleration (supporting rotation, scaling, mixing, etc.); dedicated sensor acquisition peripherals (with its own 40KB FIFO and supporting preprocessing) supporting SPI, I2C and other interface methods; DCMI camera interface and I2S audio peripherals All pretty good too.
