PMIC - Supervisors
The TPS3806I33DBVR is a progressive power supply supervisor which is a part of a number of integrated chips by Texas Instruments. It is useful in a great range of applications such as integrated power systems, high power processors and other components. This supervisor provides an array of features including programmable power-up/down sequencing, programmable power supplies, precision power-on-reset, and ultra-low quiescent current for lithium battery operation. This article will provide an overview of the application fields and working principle of the TPS3806I33DBVR.
Application Fields
The TPS3806I33DBVR is a versatile supervisor designed for a variety of applications. It is best suited for applications that require a precise power-on-reset (POR) as well as accurate power-up/down sequencing. It is ideal for integrated power systems with multiple voltage sources, and it is also suitable for high power processors, micro-controllers, and other components that require monitoring of system activity. Additionally, this supervisor includes an ultra-low quiescent current circuit that allows for efficient operation with lithium batteries.
This supervisor is also well suited for applications that require precise voltage monitoring, including better than 1% accuracy over a wide range of input voltages. It is often used in portable and embedded systems, as well as in SMPS’s, DC/DC converters, and UPS’s. Moreover, a full suite of protections, including thermal shutdown and overcurrent, is available to ensure reliable operation in potentially dangerous conditions.
Working Principle
The TPS3806I33DBVR works on the same principle as all progressive power supply supervisors. It monitors the input voltage and adjusts the output power to ensure maximum efficiency. The supervisor is equipped with an operational amplifier, comparator, and voltage reference that constantly monitors the input voltage and compares it to the output power. When the feedback loop is closed, changes to the output power are reflected in the input voltage.
The TPS3806I33DBVR also includes a number of features that allow for customization of the power output. Programmable power-up/down sequencing allows for timing of individual power supplies, while accurate power-on-reset provides fast response to over voltage and under voltage conditions. The ultra low quiescent current circuit gives exceptionally low power usage while still providing reliable operation. Additionally, a wide array of protection features are available, including temperature monitoring and over current protection, offering a versatile and reliable supervisor.
In short, the TPS3806I33DBVR is a progressive power supply supervisor designed for use in a variety of applications. Its accurate power-on-reset, programmable power-up/down sequencing, and ultra-low quiescent current circuit make it ideal for integrated power systems, high power processors and other components that require monitoring of system activity. Additionally, its full suite of protections provide reliable operation in dangerous conditions.
