S-13R1H31-A4T2U3 Application Field and Working Principle

S-13R1H31-A4T2U3, manufactured and marketed by the Johnson Technology Corporation, is a PMIC, or power management integrated circuit, that falls into the linear voltage regulators category. It is designed for local and point-of load regulation and is suitable for a range of input sources, from 4V to 26V.

S-13R1H31-A4T2U3 is a three-channel device composed of three sequentially connected regulators. It provides a total output current of up to 3A. Each channel is independently adjustable and provides output current ratings of 0.25A, 0.5A, or 1A.

The device features optimized transient-response characteristics and low rippling, enabling excellent regulation over a wide dynamic range. The regulator outputs are adjustable between 2.85V and 15V with a minimum current limit. It also features integrated protection features including thermal shutdown, over-temperature, and over-current protection.

The device operates on a wide supply voltage, from 4V to 26V, making it suitable for applications that require higher power supply outputs. It has an adjustable fixed-frequency PWM controller for regulating output voltage, so that the device can be used in applications with extreme current, voltage, and noise requirements.

The device provides over-current protection from shorted or overloaded outputs, as the regulators are designed to shut down the current path if the current through it exceed a certain threshold. The S-13R1H31-A4T2U3 also has thermal protection, so that if the temperature inside the device rises too high, the device will shut down to protect itself. It also features over-voltage protection, which prevents the output voltage from getting too high due to a fault or an overload.

The S-13R1H31-A4T2U3 can be used in a variety of applications, including servers, surveillance equipment, routers, and industrial control systems. It can be used in both power delivery and surge protection applications, as it provides reliable protection against over-voltage and over-current. It also provides excellent protection against voltage and current fluctuations, making it suitable for wide range supply rail applications.

The device’s robust design and reliable protection features make it an ideal solution for high-current and high-voltage applications requiring regulation and protection from transients, current shorts, and over-voltage conditions. With its wide input voltage range and adjustable output voltage range, the S-13R1H31-A4T2U3 provides excellent power sequencing, sequencing control, and output control.
