Frequently Asked Questions

What reset delay options are available on the PTLV840NADL29DBVR?

The PTLV840NADL29DBVR features a programmable reset time delay, meaning the delay can be set via an external capacitor or resistor network depending on the specific variant. This allows designers to accommodate slow-rising power supplies and avoid false resets during initial power-up sequences in sensitive embedded systems.

What package does the PTLV840NADL29DBVR use?

The device comes in a 5-pin SOT-23 package (JEDEC code R-PDSO-G5), one of the smallest surface-mount packages available. The SOT-23 footprint measures approximately 2.9 mm × 1.6 mm, making it suitable for compact PCB designs in wearables, portable devices, and densely populated boards.

Is the reset threshold fixed or adjustable on the PTLV840NADL29DBVR?

The PTLV840NADL29DBVR has an adjustable threshold, as indicated by the 'Adjustable Threshold: YES' specification. This allows the designer to set the precise voltage at which the supervisor triggers a reset, offering flexibility compared to fixed-threshold supervisors when monitoring non-standard supply voltages.

What additional functions does the PTLV840NADL29DBVR support beyond basic reset?

Based on the available specifications, the PTLV840NADL29DBVR supports programmable reset delay (PRG RST DLY: Y) as its primary additional feature. It does not include watchdog, manual reset, overvoltage detection, or power-fail inputs and outputs, keeping the design simple and the package footprint minimal.

When was the PTLV840NADL29DBVR introduced and is it still active?

The PTLV840NADL29DBVR was introduced on 2020-03-01, making it a relatively recent product with active production status. Being a newer device, it is expected to have a long lifecycle ahead, reducing supply continuity risk for new designs compared to older legacy supervisors.
