Texas Instruments TPS3307·18 TPS3307·25 TPS3307·33 Specifications Manual User Guide
Summary
The TPS3307 family provides high-reliability, micropower supply voltage supervision for complex digital systems requiring multiple power rails. This series monitors three independent voltages (SENSE1 through SENSE3), issuing a reset signal to ensure proper initialization during power-up or voltage dips in demanding environments. The technical document details the operational specifications, including fixed delay mechanisms and adjustable thresholds. Ideal for engineers developing industrial controls, automotive electronics, portable devices, and DSP/microcontroller-based systems where reliable system startup is mission-critical.

Frequently Asked Questions
What is the operational temperature range for this supervisor?
The devices operate over a temperature range of –40°C to +85°C.
How does the RESET output behave during power-on or monitoring?
On power-up, RESET is asserted when V > 1.1V. It remains active (low) as long as SENSEn remain below the threshold voltage V.
Does external adjustment of sense voltages occur?
Yes, the actual sense voltage must be adjusted by an external resistor divider according to the application requirements.
What is the time delay for RESET deactivation after power-up?
The internal timer delays the return of the RESET output to active (high) state; the delay time is 200ms.
