L5-25421-22 is a general purpose linear current sensor IC for detecting the current through the current shunt resistor and providing the corresponding voltage across the sensor resistor. It is most commonly used in the current detection applications in automotive applications like: battery management systems, power steering systems, electrical power sentry systems, fuel pump monitoring systems, air-bags deployment systems, door/window open/close sensing systems, and alternator/starter monitoring systems to name a few.

The linear current sensor IC (L5-25421-22) utilizes a low-resistance, integrated current shunt resistor that is commonly termed a “galvanic shunt” in many automotive applications. This galvanic shunt is an inexpensive, reliable and accurate current-sensing element that is designed to measure the current flowing through it, and then provide a corresponding voltage that is proportional to this current. The chip measures the current through the shunt and then amplifies the results with its proprietary signal conditioning circuitry, which enables it to measure DC currents up to a maximum of 15 milliamps. The output voltage produced is also proportional to the current flowing, and this output voltage can be monitored or used to control the electronic circuit.

The working principle of the linear current sensor IC (L5-25421-22) is simple. The integrated current sensing shunt resistor receives the current that is to be measured and then produces a voltage drop which is proportional to the current flowing through it. This voltage drop is then amplified by the internal amplifier circuitry, which produces an output voltage that is proportional to the current flowing through the shunt. The output is then further processed and the corresponding voltage can be read from the output of the chip. This voltage is then further converted to a digital signal which can be used for monitoring or controlling the system.

The linear current sensor IC (L5-25421-22) is a versatile IC that can be used in many applications. It is most commonly used in automotive applications for current detection. It can also be used in industrial and commercial current monitoring systems. It is offering linear characteristics with accurate current and voltage measurements and can be operated over a wide temperature range. This chip also provides temperature compensation which ensures that the measurements remain accurate even when the ambient temperature changes significantly. It is a robust, low-power device and can be used in combination with analog-to-digital converters for further processing of the signal.
