- Manual reset input combined with programmable reset time delay providing flexible system startup and fault recovery control
- Compact 5-pin SOT-23 package enabling space-efficient voltage supervision in portable and space-constrained designs
Applications
The PTPS3840DL27DBVR is used in microcontroller and processor-based systems requiring reliable power-on reset and brownout detection with minimal power overhead. Its programmable reset time delay is valuable in systems where the power supply requires a defined settling time before the processor is released from reset. The device is well-suited for battery-operated IoT nodes, wearables, and portable instruments where supply current must be minimized.

Frequently Asked Questions
What is the key function of the PTPS3840DL27DBVR?
The PTPS3840DL27DBVR is a nanopower voltage supervisor that monitors a supply voltage and asserts a reset signal when the supply falls below a fixed threshold of 2.7V. It includes a manual reset input and a programmable reset time delay for flexible system initialization.
What makes the PTPS3840DL27DBVR suitable for battery-powered applications?
The PTPS3840DL27DBVR is designed with nanopower quiescent current, making it ideal for battery-powered and energy-harvesting systems. Its minimal standby power consumption ensures it does not significantly impact battery life in always-on supervisory roles.
What package does the PTPS3840DL27DBVR use?
The PTPS3840DL27DBVR is housed in a 5-pin SOT-23 package (JESD-30 code R-PDSO-G5) with a small outline, low-profile, shrink-pitch design. This compact SMD package is suitable for space-constrained designs and is compatible with standard tape-and-reel automated assembly.
Can the reset threshold of the PTPS3840DL27DBVR be adjusted?
No, the PTPS3840DL27DBVR has a fixed (non-adjustable) reset threshold. The '27' in the part number indicates a fixed 2.7V supervision threshold. For designs requiring a different threshold, Texas Instruments offers other variants in the TPS3840 family with alternative fixed thresholds.
