S-13R1C26-I4T1U3 Datasheet/PDFThe S-13R1C26-I4T1U3 is a voltage regulator, specially designed for automotive on board applications. It is a linear regulating device with a wide input voltage range supported, and can ensure a stable output voltage when voltage fluctuations occur. Besides, it is constructed as a multi-output IC and is able to provide a variety of output voltage settings.
The S-13R1C26-I4T1U3 belongs to a group of PMIC (Power Management Integrated Circuit) voltage regulators and is considered as a high-efficiency, low-output device with the ability to meet a variety of requirements for automotive power supply for both pre-engine start and post-engine start. It is an ideal choice for vehicles that require voltage accuracy to be maintained for a safe and continuous operation.
In terms of the application field, the S-13R1C26-I4T1U3 can be used in all kinds of automotive on board applications such as fuel injection systems, airbags, exhaust gas recirculation systems, air conditioning systems, navigation systems, electronic control units, and ECU/ECMS. These systems usually require a wide voltage input range between 4.2V to 70V and an output voltage of 3.3V, 5V, 12V, or another fixed voltage.
The S-13R1C26-I4T1U3 is based on a linear regulator technology, enabling it to provide a stable, continuous, low output voltage. This technology is implemented by the use of a resistor of a certain value, and a transistor, which are connected in series between the input voltage and the output voltage. This type of voltage regulation also includes a monitoring circuit and a feedback loop system to provide protection against overcurrent and over-voltage.
The resistor works in conjunction with the transistor to maintain a defined output voltage when a voltage fluctuation occurs in the input voltage. When the input voltage is higher than the output voltage, the current flows through the resistor and the transistor, causing the voltage to drop until it reaches the output voltage level. Conversely, when the input voltage is lower than the output voltage, the current flows from the output to the input, which raises the voltage until it reaches the output voltage.
In addition, the S-13R1C26-I4T1U3 features a built-in monitoring circuit, which offers a number of protection functions. This circuit is able to detect any over-current or over-voltage and will then shut down the output if these conditions occur. This minimizes potential damage to the components connected to the voltage regulator and avoids any hazardous situations which could potentially occur.
Finally, the S-13R1C26-I4T1U3 is able to provide multiple output voltage settings to meet a variety of applications. This feature allows the device to be used in a wide range of automotive on board applications and provides an excellent level of flexibility for its users.
