This reference design is an automotive-qualified isolated gate driver solution that drives silicon carbide (SiC) MOSFETs in a half-bridge configuration. This design provides two push-pull bias supplies for dual-channel isolated gate drivers, each providing +15V and –4V output voltages and 1W output power. The gate driver is capable of 4A peak source current and 6A peak sink current. The driver implements reinforced isolation and can withstand 8kV peak isolation voltage and 5.7kV RMS isolation voltage as well as common-mode transient immunity (CMTI) of over 100V/ns. This reference design includes a two-stage shutdown circuit that protects the MOSFET against voltage overshoot during short circuit conditions. DESAT detection threshold and second stage shutdown delay time are configurable. This design uses an ISO7721-Q1 digital isolator to connect the fault and reset signals. The overall design adopts a compact double-layer PCB board of 40mm × 40mm.
This TI reference design provides a low-component-count, low-cost solution for a 4 to 20mA loop-powered resistance temperature detector (RTD) temperature transmitter. The design utilizes the on-chip smart analog combination module in the MSP430FR2355 MCU to control the loop current, thus eliminating the need for a separate DAC. The design achieves 12-bit output resolution and 6µA output current resolution. The design incorporates reverse polarity protection as well as IEC61000-4-2 and IEC61000-4-4 protection on the loop power input.
This reference design boosts a single-cell battery voltage to a 10W output using the MAX669 controller in the bootstrapped mode.
This reference design provides design guidelines, data, and more for a 1kW server power supply using a phase-shifted full-bridge DC-DC converter.

Bidirectional Isolated High-End Current Sense Module with 270 V Common-Mode Rejection
The TIDA00255 reference design utilizes the bq76940 analog front end (AFE) IC. It can measure battery voltage, mold temperature or external thermistor voltage using a 14-bit ADC. Current is measured individually by a separate 16-bit coulomb counter. The design turns off the low-side power FET to stop discharging or charging based on selected hardware limits. A microcontroller not included in this design will be part of the battery controller to communicate with the AFE to set protection thresholds, enable the power FETs, provide fault recovery, and shut down the FETs during over/under temperature conditions. Battery controller designs may include additional features that are not part of this reference design, such as secondary overvoltage protection, measurement, and isolated communications to inform the system of battery status.
The Acontis EC-Master EtherCAT Master stack is a highly portable software stack that can be used on a variety of embedded platforms. EC-Master supports high-performance TI Sitara MPUs and provides an advanced EtherCAT Master solution that customers can use to implement EtherCAT communication interface boards, EtherCAT-based PLCs or motion control applications. The EC-Master architecture is designed so that users do not need to plan additional tasks, so the full stack functionality is available even on platforms without an operating system (such as TI Starterware supported on AM335x). This architecture combined with high-speed Ethernet drivers allows users to implement EtherCAT master on the Sitara platform with very short cycle times of 100 microseconds or less.
This antenna board reference design contains multiple low-cost antenna solutions for sub-1 GHz and 2.4 GHz short-range wireless systems.
