LP5305A 過電壓電流保護(hù)IC 微源現(xiàn)貨
General Description
LP5303A is a single-channel overvoltage and programmable overcurrent protection device. The device integrates powerful protection and diagnostic functions to ensure the voltage and current stability of the output port, even in the event of harmful events such as input overvoltage, overcurrent and so on. In the mean while the device has short-circuit and thermal shutdown protection functions, which can be safely Turn off the output. The device also supports external adjustment of the current limit. This feature Performance by reducing the inrush current when driving large capacitive loads and as much as possible Overload current can improve the reliability of the system, thereby eliminating system undervoltage condition. The device protects against faults through reliable current limiting. According to different device requirements, the corresponding safe current set point can be configured to make the chip react to over-current events to protect the circuit system.
