The three voltage thresholds are set at 2.93 V, 4.55 V, and an adjustable input — a common combination for tracking a 3.3 V core rail, a 5 V I/O rail, and a third supply that can be set with an external resistor divider. ## Voltage thresholds and rail coverage The 2.93 V threshold monitors a 3.3 V rail with roughly 370 mV of hysteresis below nominal — enough margin to catch a brownout before the downstream logic glitches. The 4.55 V threshold covers a 5 V rail, and the adjustable input lets you monitor a 1.8 V, 2.5 V, or other intermediate rail without a second supervisor IC. The push-pull, totem-pole output drives CMOS logic inputs directly; no external pull-up resistor is needed. Both active-high and active-low reset signals are available, so the part can interface with processors that require either polarity.","metaTitle":"TPS3307-33DRG4 Multi-Voltage Supervisor, 2.93V/4.55V/Adj","metaDescription":"Texas Instruments TPS3307-33DRG4 multi-voltage supervisor monitors 3.3V and 5V rails.

The -33DR variant shares the same pinout and thresholds, so it is a direct functional replacement. Confirm the package code matches your board footprint."},{"question":"What is the typical application for a multi-voltage supervisor like TPS3307?","answer":"It is used in systems with multiple supply rails — DSPs, FPGAs, or microcontrollers that require a 3.3 V core and 5 V I/O — to ensure all rails are within tolerance before the processor is released from reset. The adjustable channel adds flexibility for a third rail."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS3307-33DRG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS3307-33DRG4 when reusing this data.
