TPS3106K33DBVR

TPS3106K33DBVR is the K33 variant of a dual-input voltage supervisor in a SOT-23-6 (DBV) package: the main VDD threshold is 2.941 V, and a separate SENSE input with its own RSTSENSE output monitors a second rail or signal. The power-on reset delay is 130 ms, quiescent current is a typical 1.2 µA, the output is open-drain and active-low, a manual reset input is included, and the supply range is 0.9 V to 3.6 V across -40 C to +125 C. Monitoring two rails with one device suits processor-plus-core and other dual-supply designs, and the microamp draw keeps it viable in battery-backed equipment. Selection advice: note that this device has no watchdog timer; designs that need watchdog supervision must pick a supervisor family that integrates one, rather than assuming the function is present. Confirm the K33 threshold against your rail plan before ordering. Parameters verified against Texas Instruments documentation.
