Frequently Asked Questions
What is the threshold voltage of the TPS3128E12DBVTG4?
The TPS3128E12DBVTG4 has a fixed 1.2V threshold voltage, making it suitable for monitoring low-voltage rails in modern processors and FPGAs. The threshold is factory-set and non-adjustable, ensuring consistent performance across the full operating temperature range.
Does the TPS3128E12DBVTG4 support manual reset?
Yes, the TPS3128E12DBVTG4 includes a dedicated manual reset input pin that allows external hardware or a pushbutton switch to assert a system reset independently of the voltage monitoring function. This is useful in debug scenarios and safety-critical applications requiring forced resets.
What package does the TPS3128E12DBVTG4 come in?
The TPS3128E12DBVTG4 is available in a SOT-23-5 (5-pin small-outline transistor) package with a body size of approximately 1.6mm x 2.9mm, making it one of the most compact supervisor ICs suitable for density-critical PCB designs.
Is the TPS3128E12DBVTG4 RoHS compliant?
Yes, the TPS3128E12DBVTG4 carries JESD-609 code e4, confirming it is a fully RoHS-compliant, lead-free component with a plastic/epoxy package body. The G4 suffix in the part number also indicates compliance with Texas Instruments' green and RoHS packaging standards.
