Diodes
A diode is a two-terminal electronic component that conducts current primarily in one direction. It is made up of a semiconductor material and has the ability to allow current to pass through it in one direction while blocking current in the opposite direction. Diodes have a wide range of use cases, including rectification, voltage regulation, signal detection, and power management. They are essential components in electronic circuits and can be found in a variety of electronic devices, including computers, smartphones, and appliances. Flux.ai is the world's largest community-driven public library of diodes, with a vast collection of footprints, symbols, datasheets, and simulation models. It is a valuable resource for anyone looking to learn about or work with diodes. Whether you are a student, engineer, or hobbyist, you can find the information and resources you need at Flux.ai to help you understand and work with diodes in your projects.
LM74930QRGERQ1
OR Controller N+1 ORing Controller N-Channel 1:1 24-VQFN (4x4) The LM74930-Q1 ideal diode controller drives and controls external back to back N-Channel MOSFETs to emulate an ideal diode rectifier and power path ON and OFF control with over current and overvoltage protection. The wide input supply of 4 V to 65 V allows protection and control of 12-V and 24-V automotive battery powered ECUs. The device can withstand and protect the loads from negative supply voltages down to –65 V. An integrated high side gate control (HGATE) drives the first MOSFET in the power path. The device allows load disconnect (ON and OFF control) in case of overcurrent, overvoltage and undervoltage event using HGATE control while ideal diode controller (DGATE) drives a second MOSFET to replace a Schottky diode for input reverse polarity protection and output voltage holdup by blocking the reverse current from output to input. The device has integrated current sense amplifier which provides with an adjustable overcurrent and short circuit protection with circuit breaker functionality. The device features an adjustable overvoltage and undervoltage protection feature to protect against supply transients. LM74930-Q1 features MODE pin which can be used to selectively enable or disable reverse current blocking functionality.
