Key Features
- Fixed 3.0 V supervisory threshold with open-drain reset output for direct connection to any logic voltage rail without level-shifting
- Programmable reset delay via external capacitor allows glitch filtering and orderly power-sequencing in multi-rail systems
- Ultra-compact 6-pin WSON 1.5 mm × 1.5 mm package achieving one of the smallest supervisor footprints for space-limited IoT hardware
Applications
The TPS3899DL30DSER monitors 3.0 V supply rails in microcontroller and FPGA systems, asserting a reset signal when supply voltage falls below the threshold to prevent corrupted firmware execution during brown-out events. Its manual reset input and programmable delay capacitor make it straightforward to implement orderly power sequencing in multi-rail embedded designs. The tiny WSON package suits wearables, wireless sensor nodes, and any application where board area below 5 mm² is a design constraint.

Frequently Asked Questions
At what voltage level does the TPS3899DL30DSER assert a reset, and how is reset timing controlled?
The TPS3899DL30DSER monitors a fixed 3.0 V threshold; when the supply falls below this level, the open-drain RESET pin is asserted low within a short internal propagation delay. Reset release timing after recovery is set by an external capacitor on the CT pin, allowing programmable delays from tens of milliseconds to several seconds to ensure the regulator is fully settled before the MCU restarts.
How small is the TPS3899DL30DSER package, and why does that matter for wearable device design?
The TPS3899DL30DSER uses a 6-pin WSON package measuring only 1.5 mm × 1.5 mm, occupying roughly 2.25 mm² of PCB area. For a wearable or coin-cell-powered device where total board dimensions may be under 10 mm × 15 mm, this footprint leaves critical space for the battery, antenna, and sensor ICs without sacrificing supply supervision functionality.
Does the TPS3899DL30DSER support manual reset, and how is it triggered in a hardware design?
Yes, the TPS3899DL30DSER includes a dedicated MR (manual reset) input that pulls RESET low when asserted, independent of supply voltage. Connecting a pushbutton or an open-drain GPIO to the MR pin allows the system designer to initiate a controlled processor reset during bring-up, field debugging, or watchdog recovery scenarios without cycling board power, which is particularly useful in sealed enclosures.
Is the TPS3899DL30DSER a good fit for 3.3 V rail supervision, or should a different threshold variant be chosen?
The TPS3899DL30DSER is factory-trimmed for a 3.0 V threshold, which sits below the typical 3.3 V nominal rail and above the 2.97 V minimum for most 3.3 V regulators. If your system requires a tighter guard band, TI offers variants with 3.08 V, 3.3 V, and other fixed thresholds in the same TPS3899 family, all in the same 1.5 mm × 1.5 mm WSON footprint, allowing a pin-compatible swap without board respins.
