The FRDMCD1020EVM Evaluation Board (EVB) features the CD1020, a 22-channel switch detection interface with a programmable wetting current.
In traffic accidents, rear-end collisions occur frequently due to sudden braking of the vehicle in front. Rear-end collisions are usually caused by failure to maintain a sufficient safe distance and the brakes cannot stop the vehicle. The time from when you discover an emergency ahead to when you apply the brakes is called reaction time. The length of reaction time directly affects the length of the braking distance. Especially when driving at high speed, a serious traffic accident will occur within one second. The long reaction time does not mean that the driver is slow to react, but that he does not know whether the car in front is applying the brake lightly or hard. When he finds out, two seconds have passed, and it is very likely that he will not be able to brake. If the vehicle in front The brake lights with flashing function are different. When you see the brake lights flashing, you must be stepping on the brakes harder. At this time, you should also step on the brakes harder, and the reaction time will be shortened. Therefore, in addition to letting the car behind you know whether to apply the brake lightly or hard, the flashing brake light is also particularly eye-catching and can remind the car behind you in time.
The automotive data logger consists of NuMicro® NUC131 microcontroller and N9H30 microprocessor. NUC131 supports CAN Bus to log On-Board Diagnostics-II (OBD-II) data, which includes vehicle speed, engine RPM, engine coolant temperature, intake air temperature, MAF air flow rate and throttle position from engine control unit (ECU) simulator. Then NUC131 converts the OBD-II raw data and transmits the above information to N9H30. N9H30 shows the received information on 7” TFT-LCD human machine interface enhanced by emWin.
Nuvoton smart meter solution uses NuMicro® M2351/M2354 microcontroller based on Armv8-M TrustZone® architecture. By integrating in-house security technology, the solution provides the infrastructure for Advanced Meter Infrastructure (AMI), including device identification, communications security, remote management and secure over-the-air firmware updates (OTA).
This reference design circuit introduces a high-precision bidirectional current power supply solution used in battery test systems (BTS). The maximum current capacity is 6A, and the full-scale accuracy is less than 0.05%. Controlled by logic pins, this circuit can be used to charge or discharge the battery. During the charging process, the battery voltage can also be controlled through analog signals. Design of this circuit is simple and easy due to the fully integrated buck and boost converters. The performance of the solution can be verified via a built-in evaluation board.
This design is a 20A maximum power point tracking (MPPT) solar charge controller designed for solar panel input corresponding to 12V and 24V panels. This design is intended for small to medium power solar charger solutions, capable of operating from 12V/24V panels and 12V/24V batteries with output currents up to 20A. This design focuses on scalability and can easily be adapted to a 48V system by changing the MOSFETs to 100V rated parts. The user can also increase the current to 40A by using a TO-220 package version of the current MOSFET. This solar MPPT charge controller is designed with real-world considerations in mind, including reverse battery protection and software-programmable alarms and indications that are provided in the hardware but not configured. This design operates at greater than 97% efficiency at full load in a 24V system. For a 12V system, the efficiency is greater than 96%, which includes losses in the reverse-battery protection MOSFET.
TIDA-00261-BOOST-DRV8711 is an 8-52V, 4.5A bipolar stepper driver stage based on the DRV8711 stepper motor pre-driver and CSD88537ND dual N-channel NexFET™ power MOSFETs. This module contains everything needed to drive many different types of bipolar stepper motors and can also be converted into a dual brushed DC motor driver. The BOOST-DRV8711 is ideal for those who want to learn more about stepper motor control technology and driver stage design. This kit is designed to be compatible with all TI LaunchPads based on the LaunchPad Pinout standard, while providing primary software/firmware support for the MSP-EXP430G2 LaunchPad with MSP430G2553.
The bq25892 is a highly integrated switch-mode battery charge management and system power path management device for single-cell Li-ion and Li-polymer batteries used in a variety of smartphones and other portable devices with USB or high-voltage adapters. Its low-impedance power path optimizes switch-mode operating efficiency, reducing battery charge time and extending battery life during the discharge phase. An I2C serial interface for charging and system setup makes this device a truly flexible solution.
TI reference design TIDA-00666 supports Bluetooth Low Energy (BLE) communications and is powered by a two-wire loop capable of 4-20mA. For industrial process control instrumentation, 4mA to 20mA analog current loops are typically used to transmit analog signals. 20mA and 4mA represent the upper and lower limits of the signal range respectively. The TIDA-00666 reference design measures humidity and temperature and broadcasts the measured values via Bluetooth Low Energy technology. The TIDA-00666 design uses loop power supply, and the current value in the loop changes with the humidity value (0% is 4mA, 100% is 20mA).
