TIDA-00331
高精度功率限制解决方案
TIDA-00331
概述
This solution limits the power delivered to a maximum of 15W to ensure IEC60730 compliance in Human-Machine-Interaction (HMI) ports, making it very easy for the end equipment to meet the safety regulations.
This design uses TI’s TPS25921AD to monitor the voltage and current flowing through the connected system and controls the power output within 2%. Along with the power limit function, TPS25921AD also protect against over voltage, under voltage, inrush current and short circuits.
特性
- Precisely limits the delivered power to less than 15W
- Reduces solution size and cost while meeting requirement with increased safety and reliability
- Provides multiple levels of protection to load and bus
- No external controller and circuitry required
