Product details

Dual-rail voltage monitor — 1.4 V and 2.93 V thresholds

The TPS3306-15DGK: The reset output is open-drain, allowing multiple supervisors to share a common pull-up resistor in a wired-OR configuration — useful for sequencing multiple power domains in an FPGA or mixed-signal board. A minimum reset timeout of 70 ms holds the system in reset long enough for all regulated rails to stabilize after a brownout or power-up event before the processor begins executing code.

Industrial temperature grade and 8-VSSOP package

The 8-VSSOP package (also designated 8-TSSOP or 8-MSOP with 0.118-inch, 3.00 mm width) sits on a 0.65 mm pitch — a standard fine-pitch footprint that routes cleanly on a two-layer board with proper ground plane under the package.

The part is supplied in tube packaging; for reel or tape-and-reel quantities, confirm the ordering code suffix with the distributor at quote time.

Frequently asked questions

What supply voltage does the TPS3306-15DGK need to operate?

The TPS3306-15DGK monitors two fixed thresholds (1.4 V and 2.93 V) but the device itself requires a supply voltage within its operating range — typically 2.0 V to 6.0 V, though the exact range is not listed in the spec table; refer to the datasheet for the minimum VCC needed to guarantee the reset output state.

Does the TPS3306-15DGK have an open-drain output?

Yes, the reset output is open drain or open collector, meaning the output pin pulls low when a fault is detected but does not source current — an external pull-up resistor to the monitored rail or to the supervisor's VCC is required to define the logic-high level.

What is the closest functional alternative to the TPS3306-15DGK?

The TL7702BID is a single-voltage supervisor with a different reset polarity (active high and active low) and a propagation delay of 270 ns instead of a fixed 70 ms timeout — it is not a direct pin-for-pin replacement but can serve as a functional second-source for a single-rail application if the reset timeout and polarity are adjusted in the board design.
