Introduction to the TPS3851G33SQDRBRQ1

The TPS3851G33SQDRBRQ1 Supervisory Circuit is specifically designed as a one-time programmable voltage supervisor. It monitors the power supply voltage and provides two independent active-low reset outputs, one with a push-pull output and the other with an open-drain output. This type of device is typically used in applications such as industrial, automotive, and communication systems that require tight voltage regulation and precision monitoring.

Application Fields

The TPS3851G33SQDRBRQ1 Supervisory Circuit is designed for typical active-low system reset applications that require a reset upon power-up, power-down, undervoltage, or overvoltage conditions. It is also used in applications requiring a delayed active-low reset output. This type of device is ideal for applications that require high voltage accuracy, tight voltage regulation, and precision monitoring. It is also commonly used in applications that require protection against false trip points resulting from power supply noise or transients.

The TPS3851G33SQDRBRQ1 is also used in applications such as clock reset, watchdog timer reset, CPU reset, memory reset, and peripheral circuit reset. It is also used in microprocessor-based systems to provide an active-low reset signal at power up, detection of under-voltage and over-voltage conditions, and delayed active-low reset output. The device is also used to reset embedded controllers and DSP’s.

Working Principle

The TPS3851G33SQDRBRQ1 Supervisory Circuit is a precision device designed to monitor the supply voltage and provide a reset signal when the voltage drops or rises beyond a programmed threshold. The device features two independent active-low reset outputs, one with a push-pull output and the other with an open-drain output. These two outputs are used to reset the system or latch them at an active-high level when the voltage is monitored. The device also features an internally-adjusted reset threshold voltage, making it versatile and suitable for various types of applications.

The device is designed to detect and reset the system when the power supply voltage falls below the reset threshold voltage. The device can also be configured to reset the system when the power supply voltage exceeds the reset threshold voltage. The device also features an adjustable delayed reset timer, which allows a delayed active-low reset output.

The TPS3851G33SQDRBRQ1 Supervisory Circuit is designed to be both simple and reliable. It requires only a minimum of external components, allowing for easy integration into a variety of systems. In addition, the device is specifically designed to provide high performance and low power consumption in a variety of operating conditions, making it ideal for a wide range of applications.
