The TPS3110E15DBVRG4 is a PMIC – Supervisors device manufactured by Texas Instruments. It is a low-power, low-voltage supervisor used in critical circuit applications where reliable voltage monitoring of power lines is required. This device reduces power dissipation and extends battery life in systems with multiple power supplies. In spite of its small size and low power consumption, the supervisor provides a wide range of features to monitor multiple voltage levels in numerous applications.

TPS3110E15DBVRG4 belongs to the TI Precision family which comprises of precision analog subsystems and integrated application specific solutions for a wide range of industrial and automotive applications. This device is often used in battery powered systems and those using low voltage rails. It includes precision accuracy, low power, high-resolution cycle-by-cycle current limit and rapid transient protection.

TPS3110E15DBVRG4 has an input voltage range of 1.5 V to 5.5 V and is designed to monitor power supply voltages up to 3.1 V. It has an output type pinout with an open-drain active-low RESET signal. The device has an adjustable reset threshold voltage, an active low manual reset input pin, and an active high enable pin. It also provides adjustable open-drain reset time-out and a high sink current which is adjustable from 125 μA to 8 mA.

As per the working principle of TPS3110E15DBVRG4, it serves as a low-voltage supervisor or low-voltage reset circuit. It monitors the voltage on the VCC pin and produces a low-voltage reset signal if the input goes below the minimum value or if the VCC voltage exceeds the maximum value. This is done using a single external resistor for voltage divider setup. The reference voltage is compared with a voltage generated from the VCC pin with the comparison done continuously and in real time. The reset output is pulled low when the voltage falls below the minimum value. A low to high transition on the EN pin enables the device’s operation and a high to low transition on the MR pin initiates a reset command.

TPS3110E15DBVRG4 is suitable for applications such as voltage monitoring in low-voltage circuits, battery backup, portable devices, personal electronics, and computer system power. Other than this it can be used in designs where reliable voltage monitoring of power lines is required, as it provides a wide range of features and reduces power dissipation. It has a low-power operation of less than 2.3µA and a maximum current limit of 8 mA. These features make it suitable for use in low-voltage, low-energy systems.

Overall, the TPS3110E15DBVRG4 is a flexible, feature-rich low-voltage supervisor designed to monitor various power supplies in various applications. It is a low-power and low-voltage device with a wide range of features and adjustable parameters. This makes it suitable for use in a wide range of applications such as portable devices, personal electronics, and computer systems.
