What is TPS3707-25DGN used for?
TPS3707-25DGN is used in microprocessor and DSP supervisory circuits where reliable system startup and undervoltage reset are required, such as industrial controllers, embedded Linux boards, and communication equipment. Its power-fail output enables host processors to save state before a complete supply dropout in UPS systems and battery-backed designs. Dual-channel monitoring makes it practical for systems with both 2.5 V and 3.3 V supply rails needing simultaneous supervision.

Frequently Asked Questions
At what voltage level does TPS3707-25DGN assert the RESET signal to hold a processor in reset?
TPS3707-25DGN asserts the active-low RESET output when the monitored supply falls below the 2.25 V threshold, holding the processor in reset until the supply recovers above 2.25 V plus a built-in reset timeout delay, which prevents erratic processor operation during brownout or slow power ramp conditions.
How does the power-fail output on TPS3707-25DGN help protect data in battery-backed embedded systems?
The power-fail output on TPS3707-25DGN triggers before the main reset threshold is reached, giving the host processor several milliseconds of advance warning to flush data to EEPROM or non-volatile storage, preventing data corruption in applications such as 2.5 V-powered data loggers or industrial PLCs with backup battery supplies.
Can TPS3707-25DGN monitor two separate voltage rails on the same board simultaneously?
Yes, TPS3707-25DGN provides 2 independent monitoring channels, allowing simultaneous supervision of two supply rails such as a 2.5 V core rail and a separate I/O rail, with individual reset or power-fail outputs that can be logically OR-ed to assert a system-wide reset if either rail falls out of tolerance.
How does TPS3707-25DGN compare to a discrete reset circuit using a resistor divider and comparator in terms of accuracy?
TPS3707-25DGN integrates a factory-trimmed internal bandgap reference with a typical threshold accuracy of ±1.5%, far better than a typical ±5% accuracy achievable with a discrete 1% resistor divider and standard comparator, while also eliminating several passive components and reducing PCB area in 2.5 V processor reset circuits.
