Automotive dual-channel SiC MOSFET gate driver reference design with two-level shutdown protection

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.

15-Cell Li-Ion Battery Controller Analog Front-End Reference Design

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.

Acontis EtherCAT Master Protocol Stack Reference Design

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.

24V dual-channel brushless DC motor driver reference design for dishwasher water pumps

TIDA-00447 is a 24V, dual brushless DC (BLDC) motor drive reference design that can be used to drive circulating water pumps and drain pumps in dishwashers. The circulating water pump and drainage pump drive stages are designed for continuous operation of 100W and 30W respectively. The drain pump driver is based on a single-chip, low external component count three-phase motor driver with integrated power MOSFETs and provides a proprietary sensorless control scheme enabling continuous sine wave drive. In addition, it features an integrated buck/linear regulator that efficiently reduces the supply voltage to 5V or 3.3V to power internal and external circuitry. The circulating water pump is implemented using a discrete solution with MCU, external MOSFET driver with protection mechanism and current sensing function, and external power MOSFET. This architecture allows the flexibility to adjust drive power levels as needed. The MCU is programmed through the InstaSPIN-BLDC software, which enables sensorless trapezoidal control of the BLDC motor using an anti-EMF integration approach, and can also be used to configure and control the speed of the drainage pump stage. A separate UART interface allows the drive unit to communicate with the main user interface controller. This reference design has been fully tested with current and motor stop protection mechanisms operating at full load.
