Frequently Asked Questions
What voltage threshold does the TPS3123J18DBVTG4 monitor?
The TPS3123J18DBVTG4 monitors a fixed 1.8V supply threshold. When the monitored voltage drops below this threshold, the device asserts its reset outputs (both active-high and active-low simultaneously) to hold the processor in reset until the supply recovers and a timeout period elapses.
What reset output types does the TPS3123J18DBVTG4 provide?
The TPS3123J18DBVTG4 provides both an active-high and an active-low reset output through push-pull drivers, allowing it to directly interface with processors that require either reset polarity without additional external logic or inverter components.
Does the TPS3123J18DBVTG4 support manual reset?
Yes, the TPS3123J18DBVTG4 includes a manual reset input (MR pin) that allows an external signal, such as a pushbutton or watchdog timer, to force the device to assert its reset outputs regardless of the monitored supply voltage level.
What is the package and operating voltage range of the TPS3123J18DBVTG4?
The TPS3123J18DBVTG4 is housed in a 5-pin SOT-23 package (JESD-30 code R-PDSO-G5) and operates with a supply voltage range of 0.85V to 3.3V, making it compatible with low-voltage processor supply rails in modern embedded system designs.
