Frequently Asked Questions

What is the reset threshold voltage of the PTPS3840PL25DBVR?

The PTPS3840PL25DBVR has a fixed reset threshold of 2.5V, making it suitable for supervising 3.3V and other supply rails that must be monitored above this level.

What package does the PTPS3840PL25DBVR use?

The PTPS3840PL25DBVR comes in a SOT-23-5 (5-pin small outline transistor) package, which is a compact surface-mount package ideal for space-constrained PCB designs.

Does the PTPS3840PL25DBVR support a manual reset function?

Yes, the PTPS3840PL25DBVR includes a dedicated manual reset input pin that allows the user to force a system reset independently of the monitored supply voltage, providing extra flexibility in system design.

Can the reset time delay be adjusted on the PTPS3840PL25DBVR?

Yes, the PTPS3840PL25DBVR supports a programmable reset time delay, allowing designers to set the duration the reset signal is asserted after the supply voltage crosses the threshold, which is critical for ensuring proper microcontroller initialization.

What applications is the PTPS3840PL25DBVR suitable for?

The PTPS3840PL25DBVR is ideal for battery-powered IoT devices, wearables, industrial control systems, and embedded processor supervision applications where nanopower consumption and reliable voltage monitoring are essential.
