PMIC - Supervisors - TPS3106K33DBVR

The TPS3106K33DBVR is a special type of PMIC (Power Management Integrated Circuit) known as a Supervisory Circuit. These circuits monitor system power supplies and output signals to Systems-on-Chip (SoC) when voltages deviate from preset thresholds. Supervisory Circuits can also be used to monitor multiple voltages within a system, allowing for more precise and complete system management.

Applications of the TPS3106K33DBVR

The TPS3106K33DBVR is used in a variety of applications. It can be used in automotive systems to monitor voltage levels, check battery voltage, and reset the system if proper levels are not detected. It can also be used in medical devices to check power levels before powering up and then alert the user if needed. Additionally, this supervisor circuit is well suited for use in home appliances, industrial controls, and military systems. Any application that requires precise system management may benefit from the use of the TPS3106K33DBVR.

Working Principle of the TPS3106K33DBVR

The TPS3106K33DBVR has three pins; VCC, GND, and ON/OFF. The VCC pin is connected to the system voltage supply and is used to power the circuit. The ON/OFF pin is connected to an enable pin on the monitored system. When the enable pin is low, the circuit is disabled. The GND pin is connected to the ground reference voltage of the system. The circuit has two supply voltages; VCC and Vref. Vref is connected to an adjustable reference voltage between 2.25V and 4.63V.

The supervisor circuit monitors the voltage at its input (Vin) and compares it to the reference voltage (Vref). When the input voltage is equal to or greater than Vref, the circuit is enabled and will pull the ON/OFF pin high to indicate that the voltage is within range. If the input voltage falls below Vref, the circuit is disabled, and the ON/OFF pin is pulled low to indicate that an out-of-range voltage has been detected. Additionally, the circuit has a manual reset input and an open drain reset output. This allows for manual and/or automatic reset of the monitored system.

Conclusion

The TPS3106K33DBVR is a low-power micro-power supervisory circuit. This circuit offers a number of features that make it an excellent choice for many applications. It has low supply current, a wide range of voltage thresholds, a wide input voltage range, and an adjustable reset timeout. Additionally, it is available in a tiny 3-pin SC70 package. The TPS3106K33DBVR is used in a variety of applications and is ideal for any system where precise power monitoring and management is needed.
