What are the key features of PTLV840CADL29DBVR?
- Single-channel voltage supervisor with adjustable reset threshold for flexible rail monitoring
- Programmable reset time delay via external capacitor, avoiding false resets during supply bounce
- Manual reset input pin for firmware-controlled or push-button system resets
- 5-pin SOT-23 package enabling ultra-compact power management on space-constrained PCBs
- Designed for low-voltage systems with wide monitoring threshold adjustment range
What is PTLV840CADL29DBVR used for?
PTLV840CADL29DBVR is used in microcontroller and processor reset circuits where the supply rail must be confirmed stable before releasing the system from reset, such as in industrial PLCs, IoT gateways, and portable consumer electronics. Its adjustable delay eliminates glitch-induced resets during hot-plug events or inrush transients on 1.8 V to 5 V supply rails.

Frequently Asked Questions
How is the reset time delay on PTLV840CADL29DBVR set, and what timing range is achievable?
PTLV840CADL29DBVR uses an external capacitor connected to its delay pin to set the reset assertion time, allowing designers to tune the delay from a few milliseconds to hundreds of milliseconds, preventing false resets caused by brief supply dips or inrush transients at system power-up.
Can PTLV840CADL29DBVR handle manual reset requests from a push-button in addition to automatic undervoltage detection?
Yes. The manual reset input on PTLV840CADL29DBVR allows an external signal or push-button to assert the reset output independently of the voltage threshold, giving embedded systems a way to force a clean reboot from firmware or a front-panel control with a 5-pin SOT-23 footprint.
In what low-voltage microcontroller supply configurations does PTLV840CADL29DBVR fit best?
PTLV840CADL29DBVR supports an adjustable threshold and suits 1.8 V, 2.5 V, 3.3 V, and 5 V systems, making it appropriate for modern ARM Cortex-M MCUs, FPGAs, and DSPs that require guaranteed reset assertion before their core supply reaches the minimum operating voltage of the digital logic.
How does the SOT-23 package of PTLV840CADL29DBVR affect thermal and layout considerations?
The 5-pin SOT-23 package has a very small footprint of approximately 2.9 mm x 1.6 mm, requiring minimal PCB area. Because reset supervisors draw only microamps of quiescent current, thermal dissipation is negligible, and no heatsinking or thermal vias are needed in typical 5 V designs.
