Frequently Asked Questions
What supply voltage does the TPS3126E18DBVR monitor?
The TPS3126E18DBVR monitors a fixed 1.8V supply voltage rail with a threshold accuracy of ±1%. It operates from a supply voltage range of 2.7V to 6V and asserts an active-low RESET output when the monitored voltage falls below the 1.8V threshold, helping protect microcontrollers and processors during undervoltage conditions.
Does the TPS3126E18DBVR support manual reset?
Yes, the TPS3126E18DBVR includes a dedicated manual reset input (MR) that allows external hardware to force a system reset independently of the supply voltage level. The manual reset input features internal debounce circuitry and is compatible with open-drain or push-pull drive signals, providing flexible integration with system reset buttons or other control signals.
What is the package type and operating temperature range for the TPS3126E18DBVR?
The TPS3126E18DBVR comes in a 5-pin SOT23 (TSOT-5) surface-mount package. It is rated for operation from -40°C to +125°C, making it suitable for both commercial and industrial temperature environments. The compact footprint minimizes board space consumption while providing robust voltage supervision functionality.
What reset timeout period does the TPS3126E18DBVR provide?
The TPS3126E18DBVR provides a fixed reset timeout period of approximately 200ms after the monitored supply voltage rises above the threshold. This timeout ensures that downstream circuits have sufficient time to stabilize before the RESET signal is deasserted, preventing false starts or undefined behavior during power-up sequences in sensitive digital systems.
