Frequently Asked Questions
What voltage range does the TPS3126E15DBVTG4 monitor?
The TPS3126E15DBVTG4 monitors supply voltages from 0.85V to 3.3V, covering a wide range of modern microprocessor core voltages and I/O supply rails used in low-voltage embedded systems and IoT applications.
What type of RESET output does the TPS3126E15DBVTG4 provide?
The TPS3126E15DBVTG4 provides an active-low, open-drain RESET output which asserts when the monitored supply voltage falls below the threshold, holding the processor in reset until the supply recovers and a reset timeout period elapses.
Does the TPS3126E15DBVTG4 support manual reset?
Yes, the TPS3126E15DBVTG4 includes a dedicated manual reset (MR) input pin that allows an external push button or logic signal to assert the RESET output, enabling controlled system restarts independent of the power supply voltage level.
What package is the TPS3126E15DBVTG4 available in?
The TPS3126E15DBVTG4 comes in a 5-pin SOT-23 surface-mount package measuring approximately 2.9mm x 1.6mm, making it one of the smallest supervisor ICs available for space-constrained PCB designs in portable and wearable electronics.
