TPS3839G33DBZT

TPS3839G33DBZT application field and working principle

The TPS3839G33DBZT is a low power, low-voltage supervisor integrated with the sophisticated analog and digital logic circuits. It offers the ease of designing a low-voltage, low-power supervisor circuit without adding components. It is ideal for monitoring and detecting undervoltage conditions in systems that use inexpensive, low-power microcontrollers. The device is also well-suited for use in mobile devices, computers, digital cameras, printers, and other devices that use low-power microcontrollers.

The combination of active high-level and active low-level reset outputs, comprehensive programmability, and full-time or delayed power-on reset make the device suitable for various system reset requirements. TPS3839G33DBZT utilizes a wide input voltage range to accurately detect and monitor a system’s supply voltage and provide reliable over- or under-voltage protection.

The Low Voltage Monitor (LVM) is a 2-stage circuit that can detect voltages down to 0.45V and operates from 0.95V to 6V supply. It is designed to provide a reset signal to microcontrollers or other digital components when the supply voltage is below the user specified threshold. It\'s also capable of monitoring battery voltage in portable devices.

The TPS3839G33DBZT includes an adjustable reset threshold voltage, which allows the user to set the resetting threshold voltage according to the requirements of the specific application. The adjustable reset threshold is also configurable to delay the assertion of the reset signal, which makes the device ideal for protecting systems against sudden voltage drops. This enables the device to efficiently detect and guard against over/under-voltage events, making it suitable for preventing data loss due to power supply disturbances.

The TPS3839G33DBZT also offers innovative features like “automatic supply voltage monitoring,” allowing the device to monitor the supply voltage at regular intervals, and reset the system whenever it detects voltage levels outside a specific threshold. This increases the reliability of system designs that are vulnerable to voltage drops or spikes. In addition, the device also offers selectable watchdog and alert pins for additional safety and reliability.

In summary, the TPS3839G33DBZT is an integrated circuit designed to improve the reliability and robustness of low-power systems by providing low-voltage, low-power supervision. With its adjustable reset threshold voltage, selectable watchdog and alert pins, and automatic supply voltage monitoring, it is well-suited for a wide variety of systems that require reliable over/under-voltage protection.
