The TPS3126E18DBVT from Texas Instruments is a voltage supervisory circuit primarily intended for DSP and processor-based systems. This obsolete part monitors a single power rail and asserts a reset signal when the voltage drops below a threshold. It operates with a minimum supply voltage of 0.9V and features a fixed 180ms power-on reset delay.
The device has a typical supply current of 14µA, making it suitable for low-power applications. The TPS3126E18DBVT is available in a compact SOT-23-5 package, requiring surface mounting. Its operating temperature range is -40°C to 85°C.
This part is no longer in production. Replacements with similar or upgraded functionality are available, such as the TPS3126E18DBVR and TPS3840PL16DBVR.
