TPS3850G30DRCT is a supervisor circuit especially designed to monitor the power and ground circuitry of microprocessors and other integrated circuits that allow the system to be safely started up, shutdown and monitored in different power modes. It helps to ensure the supply voltage is always within safe parameters and that the core power domains of the processor are correctly enabled or disabled. Internally, the circuit contains voltage supervisors, which monitor that the system voltage stays within predefined limits.

TPS3850G30DRCT is designed for applications such as PC/notebook system boards, set-top boxes, embedded control, automotive applications, and industrial control equipment. It is well-suited for usage with 5V–3.3V systems, CMOS and bipolar microprocessors, and other battery-based applications.

The TPS3850G30DRCT acts through four voltage supervisors, supporting 3.3V, 2.9V, 2.5V and 0.775V. Two output pins are available for monitoring voltage rails in the +5V or +3.3V power supply range. The device also provides reset and shutdown control signals, as well as pre-programmable time-interval signals. This enables the system to safely start up and switch off, by monitoring the voltage threshold values being exceeded, within the range of operation.

As a supervisory circuit, the TPS3850G30DRCT monitors the power supply of the system, ensuring the correct voltage level at all times. It also monitors when the system enters low power or shutdown mode, and provides the control signals required to switch between the different modes. This allows the device to power up or power down the system, based on the voltage thresholds being exceeded within the range of operation. By providing time-interval signals, which can pre-programmed, it allows the system to switch on and off automatically.

In addition to providing reset and shutdown control signals, the TPS3850G30DRCT also includes a watchdog timer facility with selectable time-out intervals of ~250 ms, ~500 ms and ~1 sec. This allows the system to be monitored and controlled in order to detect fault conditions.

The circuit features an integrated voltage detector and an internal voltage regulator that ensures the correct supply voltage for the circuit. This is vital for correct system operation, as it defines the low-voltage threshold under which external interrupts are generated. The TPS3850G30DRCT also offers a voltage threshold-detection circuit, which is switched off when the output power of the system is below the defined corresponding voltage. This helps to minimize power consumption and maximize system reliability.

The TPS3850G30DRCT also provides additional features such as external reset, open drain outputs and manual reset input. It is an ideal IC for 3.3V and 2.9V battery-based applications, which require precise power rail monitoring, as well as power-on/off and reset control. Furthermore, the device helps to enhance the system’s safe and reliable operation, ensuring that the system voltage stays within predetermined limits.
