| | --| |-- |____| ```
Pin 1: GND (Ground)
Pin 2: VDD (Supply Voltage)
Pin 3: MR (Manual Reset Input)
Pin 4: RESET (Reset Output)
Pin 5: GND (Ground)
Advantages: - Low power consumption helps to conserve energy in battery-powered applications. - Wide supply voltage range makes it compatible with a variety of systems. - Adjustable threshold voltage allows for flexibility in monitoring different voltage levels. - Small package size enables space-saving designs.
Disadvantages: - Limited reset timeout period range may not be suitable for all applications requiring longer timeouts. - Open drain output requires an external pull-up resistor for proper operation.
The TPS3808G125QDBVRQ1 operates by continuously monitoring the supply voltage connected to its VDD pin. When the voltage falls below the threshold voltage (1.25V), the IC asserts a reset signal on the RESET pin. The reset signal remains active until the supply voltage rises above the threshold voltage and the reset timeout period elapses.
The TPS3808G125QDBVRQ1 is commonly used in various electronic systems where reliable power supply monitoring is critical. Some application fields include:
