Introduction

PMICs help power the electronics in our everyday life, providing cost-efficient and reliable solutions for a wide range of applications. VB325SP13TR is a selectable power switch PMIC that can control the output current and voltage for a wide range of applications. It provides a simple and cost effective power delivery solution. This article will explore the application field and working principle of VB325SP13TR.

Application Field:

VB325SP13TR is a wide voltage Integrated Power Switch (IPS) which can be used to provide up to 8A of current and up to 24V of output voltage. It is especially suitable for applications where high current, low voltage and switching speed are needed. It can be used to provide power conversion and regulation, such as powering high current loads, or providing on/off control of high power circuits.Some of the common applications of VB325SP13TR include industrial motor control systems, automotive control systems, and power electronics. It is also used in power management systems such as UPS and PDU.

Working Principle:

VB325SP13TR is an integrated power switch PMIC, which means that it combines several components into one package to provide a hassle free and cost effective solution. The integrated controller in the VB325SP13TR is responsible for regulating the output voltage and current. It is designed to switch the output voltage from an input voltage of 0-13.2V to an output voltage of 0-24V.The input voltage of the VB325SP13TR is regulated by a PWM control circuit. The control circuit consists of an internal protection circuit, an overvoltage protection circuit, and a soft-start circuit. The internal protection circuit ensures that the output voltage does not exceed the specified voltage, while the overvoltage protection circuit prevents the output voltage from exceeding the determined safe limit. The soft-start circuit is used to gradually increase the output current to prevent any inrush during start-up.Once the output voltage and current are regulated, the VB325SP13TR is able to switch the output voltage on and off with a minimum on-time of 1ms. The switching speed of the VB325SP13TR is adjustable. When the switch is activated, a pulse is sent via the enable line to activate the output voltage. When the switch is deactivated, the enable line is pulled low and the output voltage remains turned off.

Conclusion

VB325SP13TR is a selectable power switch PMIC. It is an integration of several components into one package providing an efficient and cost effective solution. It is suitable for applications where high current, low voltage and switching speed are needed. Its application field includes industrial motor control systems, automotive control systems, power management systems and power electronics. Its working principle is regulated by a PWM control circuit which is responsible for regulating the output voltage and current. It is able switch the output voltage on and off with a minimum on-time of 1ms.
