In today's rapid development of the Internet of Things and intelligent hardware, efficient and reliable motor drive technology has become the core requirement of robots, smart toys and consumer electronics. The SSP2617 single-channel H-bridge driver chip launched by Shanghai Siproin Microelectronics is redefining the performance standard of low-voltage motion control scenarios with its excellent power handling capabilities, flexible PWM control, and multiple protection mechanisms.
Today, let's talk about two very important concepts in switching power supplies -- synchronous rectification and asynchronous rectification. The switching power supply relies on the inductive charging energy storage when the power tube is opened, and the inductive energy is released when the power tube is disconnected to realize the voltage transformation. After the power tube is disconnected, the inductance releases energy to have a current loop, which is different in the selection of current components, it will involve different rectification methods, that is, synchronous rectification and asynchronous rectification. So what is the difference between them?
Ultrasonic heat meters are instruments that measure flow rates and display the thermal energy released or absorbed by water passing through a heat exchange system using ultrasonic methods. The device calculates the heat energy by measuring two physical quantities—the flow rate of the heat carrier and the temperature difference between the inlet and outlet—then applies compensation for density and enthalpy values and performs integration. Specifically, the ultrasonic time-difference method relies on the time difference of ultrasonic signals propagating in the fluid to measure flow rates.
Input voltage (withstand voltage): it refers to the voltage range of 78L33 Vin. If the input voltage is higher than the maximum working voltage of 78L33, it will exceed the voltage withstand degree and damage. If the input voltage is lower than the minimum working voltage of 78L33, then 78L33 will not work properly.
Many engineers in the choice of BOOST type DC-DC chip found that even if the chip with the enable function, still can not turn off the system, the output voltage or follow the input voltage exists, at this time the consumption current follows the load changes, in this state will not only continue to consume power, but also the risk of damage to the post-stage circuit.
RS485 circuit is a common serial communication interface standard, widely used in industrial control environment. It uses balanced transmission and differential reception, has the ability to suppress common-mode interference, is suitable for the communication distance from tens of meters to thousands of meters, and performs well in multi-node systems.
