Product details

Dual-rail supervisor with fixed thresholds

The TPS3306-15D is a dual-voltage supervisor from Texas Instruments that monitors two supply rails simultaneously, with fixed thresholds of 1.4V and 2.93V. This eliminates the need for external resistor dividers when monitoring common logic rails like 3.3V and 1.2V or 1.8V. The active-low reset output is open-drain, allowing multiple supervisor outputs to be wire-OR'd to a common reset line and enabling level-shifting to higher or lower logic voltages via an external pull-up resistor.

Frequently asked questions

Does TPS3306-15D require external pull-up resistors?

Yes — because the output is open-drain, a pull-up resistor to the desired logic voltage (e.g., 3.3V or 5V) is required for the reset signal to reach a valid high level. The resistor value is typically 10 kΩ, but the exact value depends on the load capacitance and desired rise time.

What is the difference between TPS3306-15D and TPS3306-18D?

Both are dual-voltage supervisors with the same package and output type. The difference is in the monitored thresholds: TPS3306-15D monitors 1.4V and 2.93V, while the TPS3306-18D monitors 1.4V and 1.8V. Choose based on the supply rails in your system.
