Key Features
- Nanopower quiescent current enabling always-on supply monitoring in battery and energy-harvesting powered IoT systems
- Fully programmable sense threshold and reset delay for flexible voltage supervision without fixed-voltage-version inventory management
- 6-WSON ultra-small package with -40°C to 125°C operating range for harsh industrial and automotive environments
Applications
TPS3899DL08DSER is used in embedded processor and FPGA power sequencing designs where each supply rail must reach its operating threshold before releasing the reset line. Its adjustable threshold accommodates non-standard supply voltages such as 1.05V, 1.8V, or 2.5V core rails in SoC designs without requiring a library of fixed-threshold supervisors. Industrial PLCs, automotive ECUs, and medical device controllers rely on this device for reliable power-on-reset and brown-out detection across the full -40°C to 125°C temperature range.

Frequently Asked Questions
How do you set the reset threshold voltage on TPS3899DL08DSER for a 1.8V supply rail?
TPS3899DL08DSER uses an external resistor divider connected to its SENSE pin to program the trip threshold. For monitoring a 1.8V rail, select resistor values so the divider output equals the internal 0.4V reference at 1.8V. A 10 kΩ and 2.86 kΩ resistor pair sets the threshold close to 1.8V, with the 0.4V internal reference providing the precision voltage reference for comparison.
What temperature range does TPS3899DL08DSER cover and for which harsh-environment designs is it qualified?
TPS3899DL08DSER operates from -40°C to 125°C, covering both industrial and automotive temperature grades. This full range makes it suitable for under-hood automotive ECU power management, outdoor industrial controllers, and factory automation equipment that must start and operate reliably from cold winter start-up to high-ambient-temperature continuous operation without reset glitches.
How does TPS3899DL08DSER programmable reset delay prevent nuisance resets during power supply transients?
TPS3899DL08DSER allows an external capacitor on the CT pin to program the reset delay from a few milliseconds up to seconds. By selecting a capacitor that sets a 100 ms delay, brief supply dips shorter than 100 ms caused by load transients do not trigger a system reset, preventing unnecessary microprocessor restarts that would disrupt industrial process control or data logging applications.
In what way does the 6-WSON package of TPS3899DL08DSER benefit space-constrained designs compared to SOT-23-5?
The 6-WSON package used by TPS3899DL08DSER measures approximately 2 mm x 2 mm, which is smaller than an SOT-23-5 package and provides an exposed pad for improved thermal dissipation. This form factor is valuable in compact IoT modules, smartwatch charging circuits, and wearable medical patches where PCB area is measured in fractions of a square centimeter.
