TIDA-00334: TI design TIDA-00334 wireless power supply transmitter is an application of the bq500212A IC in a small form factor design targeted at low power wearable devices. Input voltage to the unit is 5V from a Micro USB connector. The low power design will support output power at the receiver up to 2.5W. All key transmitter circuits are laid out in a 30mm area which matches the diameter the Wurth coil P/N 760308101103. This area is slightly larger than a US Quarter or 2 Euro coin. PCB is 38mm X 76mm (1.5” X 3.0”) but area for the circuit is inside the 30mm coil diameter is about 700mm2.

TIDA-00302: This high-side current shunt monitor is used to measure the voltage developed across a current-sensing resistor when current passes through it. Additionally, an external protection circuit is implemented to provide surge and fast-transient protection and demonstrate the different immunity levels to IEC61000-4-4 and IEC61000-4-5.

TIDA-00753: The TIDA-00753 reference design demonstrates high accuracy wide range AC current measurement for a three phase motor using the INA199 zero drift current shunt monitor. The design also has low power consumption of 25mW for Gain stage of 200 as compared to a discrete solution. The design footprint and BOM cost is much smaller than a discrete solution due to the integrated high precision resistors inside the INA199.

TIDA-00748: TIDA-00748 is a 60W Synchronous Boost Design for automotive LED application utilizing the Synchronous Boost Converter LM5122-Q1. This design applies to automotive lighting for exterior lighting such as headlights and taillights and also interior LED lighting systems. The design accepts an input voltage of 8Vin to 15Vin and can drive multiple strings of 6 to 7 LEDS (16V to 24V) in series at 3A constant current. It is a low cost solution and provides undervoltage as well as overvoltage protection. This solutions offers 97% efficiency compared to inefficient nonsynchronous Boost solutions. The TIDA-00748 can also be modified to a Boost-to-Battery configuration by connecting the cathode of the LED string (9V to 12V) to the input rather than ground and connecting the output capacitors from input to output. In this configuration, the 8V to 15V input can power strings of LEDs that require voltages lower than, higher than, or equal to the input voltage which would not work with the standard Boost configuration which requires the output voltage to be higher than the input voltage. See Figure 1 for the Boost-to-Battery configuration along with the internal block diagram of the LM5122.
