The TPS3808G50DBVRG4 offers the following functional features:
Advantages: - Low power consumption - Wide operating voltage range - Programmable delay time - Small package size
Disadvantages: - Limited number of available threshold options - Lack of adjustable hysteresis
The TPS3808G50DBVRG4 operates by continuously monitoring the supply voltage using an internal voltage reference. When the supply voltage falls below the programmed threshold, the reset output is asserted, indicating a power failure or low voltage condition. The manual reset input allows for external control of the reset signal. The watchdog timer monitors system activity through the WDI input and resets the device if no activity is detected within the programmed timeout period. Upon power-up, the power-on reset generator ensures that the system starts in a known state.
The TPS3808G50DBVRG4 is commonly used in various applications, including but not limited to: - Battery-powered devices - Embedded systems - Industrial automation - Consumer electronics - Automotive electronics
