Inrush Current Limiters (ICLs) are a kind of tool used in the field of electronics to help restrict the current that flows into a circuit upon initial power-up or a change in load. When powered on, circuits can draw large levels of current - up to many times the normal operational level. This sudden burst of electric power can cause several different kinds of problems, from short circuits to dangerous power overloads. To protect circuits from these risks, an Inrush Current Limiter like the ST10003B can be used.The ST10003B is a type of electronic component designed to limit the current when the equipment is powered on or the load is changed. It does this by delaying the current for a certain period of time, allowing the voltage to rise slowly and allowing the circuit to be powered up smoothly. The device consists of a bypass resistor and a shunt regulator, which works together to ensure that the circuit has safe and stable operation over the long-term. The resistor is used to decrease the current when the voltage rises, while the shunt regulator acts as a switch to control the flow of current.When the ST10003B is enabled, it works in two stages. The first stage is a Pre-Charge Mode, where the device slowly increases the voltage from zero up to the target level. This ensures that the circuit is not subjected to an excessive current spike. During this process, the bypass resistor reduces the current back to its normal operation level. The second stage is an On-Treshold mode where the device maintains the voltage of the circuit until it reaches the target level. This ensures that the current stays at the desired level and prevents any voltage spikes.The ST10003B is a practical and reliable component that is used in various electronic applications. It has an adjustable hysteresis to provide flexibility in protection. It is typically used in power supplies, battery chargers, LED circuits, and other applications that require reliable and adjustable current limiting. The device ensures that the power supply is stable, safe, and efficient, while also reducing the risk of overloads, overheating, and circuit destruction.Overall, the ST10003B is a versatile and reliable Inrush Current Limiter that is highly effective in protecting circuits from excessive current and voltage surges upon power on or a change in load. It provides an adjustable current limit and can be used in a variety of applications. For added reliability, the device has an adjustable hysterisis that can be adjusted to provide additional protection. This makes the ST10003B an ideal choice for a wide range of circuit protection applications.
