TLC7701QPWR Application Field and Working PrinciplePower supply management or power management ICs, such as the TLC7701QPWR, are essential components of many modern systems. These PMICs provide the necessary platform for efficient and reliable power management in order to allow for optimized operation of the system it regulates. In this article, we will discuss the application fields and working principle of the TLC7701QPWR PMIC.The TLC7701QPWR is classified as a PMIC – supervisor and belongs to the Texas Instruments line of precision voltage monitoring ICs. It was specifically designed to be used as a high-accuracy, low-power supervisor and power-on reset device in space-constrained consumer applications.The TLC7701QPWR features an accurate voltage threshold reference and an integrated delay circuit, both of which are programmable through external resistor values. It is stable for power supply voltages between 1.4V and 5.5V and provides a high accuracy of ±3% voltage reference. The output voltage can be set to any point within a range from 1.2V to 5.5V. Additionally, the TLC7701QPWR has a low quiescent current of less than 200 µA; its extremely low operating power and current consumption make it a desirable choice for battery-powered applications.The working principle of the TLC7701QPWR is simple yet effective. It features a precision voltage reference circuit, open-drain reset output, and an internal delay circuit. The built-in reference circuit is capable of accurately detecting any changes in the regulated voltage. When a steady-state regulated voltage is lower than the preset threshold voltage, the open-drain reset output is activated. The delay circuit accounts for the necessary output delay, allowing the regulator output voltage to properly stabilize.In terms of applications, the TLC7701QPWR is most commonly used in consumer systems such as PCs, cell phones, and other handheld devices. Its capability of detecting and responding to changes in input voltage makes it an integral component in these systems. By providing a low-power solution for power supply management and reset generation, the TLC7701QQWR proves to be a dependable component that allows for the seamless operation of the device.In conclusion, the TLC7701QPWR PMIC – supervisor is a reliable component that allows for the efficient and effective management of power in space-constrained consumer applications. Its accurate voltage threshold reference, integrated delay circuit, and low quiescent current make it a desirable choice for battery-powered systems. It finds its application in consumer systems such as PCs, cell phones, and other handheld devices, making it an essential component in these systems.
