MAXREFDES1153: Multi-cell fuel gauge with battery protection and balancing circuit using MAX17205

The MAXREFDES1153 is a monitoring solution for genuine lithium-ion (Li+) battery packs with 2 to 15 cells connected in series. This reference design provides an accurate state of charge (SOC) in milliamp-hours (mAh) or percentage (%), as well as precision measurements of current, voltage, and temperature for multicell battery packs.

Proximity switch reference design using CapTIvate teaching button

This reference design demonstrates how to implement a capacitive touch button, commonly used as a setting button in a proximity switch, in an ultra-small 3.5mm wide PCB based on TI's CapTIvate™ technology. When combined with the highly integrated IO-Link PHY, flexible PNP or NPN outputs are possible. The SIO stage provides reverse polarity, ESD, EFT and surge protection, making the design compliant with IEC 61000-4 standards. Hall sensors with analog output signals enable flexible use by teaching the distance to magnetic objects via a capacitive teach button. This analog signal is captured by the MCU's integrated ADC.

Ultra-small 1W, 12V-36V isolated power supply reference design for analog programmable logic controller modules

Analog input and output modules are standard components of programmable logic controllers (PLCs) or distributed control systems (DCS). In these modules, the increasing number of channels per module and the thinner and thinner modules present design challenges for isolated power supplies. All designers facing these challenges will benefit from the TIDA-00237 as its total design size is less than 2.54x2.54mm and its height is less than 5mm. It uses a flyback approach, which means no optocoupler feedback is required, and has a wide input voltage range of 12V-36V. This design provides +/-15V and 5V isolated low-noise outputs, making it ideal for driving data converters or analog front ends.
