TPS3808G50QDBVRQ1

TPS3808G50QDBVRQ1 application field and working principle of PMIC - Supervisors is an integral part of today\'s electronics. The device supports a range of DC/AC power supply configurations for smart phone, tablet and application processor designs. It supervises power-on reset (POR), operation reset (OR) and other reset functions to ensure system stability and reliability. Moreover, the device provides very low quiescent current (12μA), low noise operation, and programmable reset types.

In portable electronic devices, proper power management is critical. To accomplish this, engineers must optimize the power supply configuration without sacrificing system performance or reliability. This is where the TPS3808G50QDBVRQ1 comes in. The device offers a fast, programmable reset pulse to the board, ensuring reliable operation in the event of electrical or thermal system faults. Moreover, the device provides very low quiescent current, which helps minimize power usage and extending battery life in portable applications.

The TPS3808G50QDBVRQ1 supports both push-pull and open-drain reset outputs and includes adjustable reset thresholds for improved system safety. The device also includes logic-level feedback for improved system monitoring, off-chip programmable reset delay time and configurable active-low/high reset outputs. The device is also equipped with a low-leakage capacitor for improved performance in high-temperature applications. Additionally, with its momentary on/off conditions, the device is ideal for applications requiring reset timeout on system power-up.

The working principle of the TPS3808G50QDBVRQ1 involves several steps. First, when the supply voltage reaches the reset threshold, the device’s internal voltage regulator pulls the RESET pin high. Then, the device delays for a programmable interval before it issues a reset pulse. During the reset interval, the device monitors the supply voltage to ensure it remains above the reset threshold. If the threshold is exceeded, the device issues a reset pulse. After that, once the reset phase has been completed, the device monitors the supply voltage until it reaches the trip threshold either due to temperature changes, current limit, system faults or other events.

In addition to its reset functions, the TPS3808G50QDBVRQ1 also offers additional protection features. The device allows users to configure various settings such as overvoltage, undervoltage and overcurrent protections. There is also an adjustable reset timeout to prevent the device from resetting prematurely in case of momentary power dips or an on/off event. All together, this makes the TPS3808G50QDBVRQ1 an ideal solution for powering and monitoring circuits in smart phone, tablet, application processor and other portable devices.

The TPS3808G50QDBVRQ1 offers a robust, reliable solution for power management and reset functions for portable and other applications. With its low quiescent current, multiple reset and power monitoring capabilities, this device ensures reliable and safe operation for any circuit.
