Frequently Asked Questions
What voltage does the TPS3123G15DBVRG4 monitor?
The TPS3123G15DBVRG4 monitors a 1.5V supply rail with a fixed threshold. It is designed specifically for ultra-low voltage processor supervision in systems using modern low-voltage microcontrollers, FPGAs, and digital signal processors running at sub-2V core supply voltages.
Does the TPS3123G15DBVRG4 include a manual reset feature?
Yes, the TPS3123G15DBVRG4 includes a manual reset input that allows external reset initiation via a pushbutton or system controller, along with an integrated power-on reset generator that asserts reset automatically when the monitored supply voltage falls below the threshold level.
What package does the TPS3123G15DBVRG4 use?
The TPS3123G15DBVRG4 is housed in a 5-pin SOT-23 surface-mount package (JESD-30 code R-PDSO-G5), one of the smallest standard IC packages available, making it ideal for compact designs in portable devices, wearables, and space-constrained embedded applications.
What is the threshold type for the TPS3123G15DBVRG4?
The TPS3123G15DBVRG4 uses a fixed (non-adjustable) threshold set at 1.5V, simplifying design by eliminating external resistor dividers. This fixed-threshold approach reduces component count and improves threshold accuracy compared to adjustable supervisor configurations.
