Frequently Asked Questions
What makes the PTPS3840PH30DBVR a 'nanopower' supervisor?
The PTPS3840PH30DBVR is characterized by an extremely low quiescent current, enabling it to monitor supply rails continuously without meaningfully impacting battery runtime, which is essential for coin-cell and energy-harvesting powered IoT and portable designs.
Can the reset delay be customized on the PTPS3840PH30DBVR?
Yes, the reset time delay is programmable via an external capacitor connected to the delay pin, allowing designers to set the exact hold-off time needed for their microcontroller or processor to reach a stable operating state after power is applied.
Does the PTPS3840PH30DBVR support manual reset?
Yes, the device includes a dedicated manual reset input that allows an external pushbutton or logic signal to force a system reset at any time, which is useful for field diagnostics and hardware fault recovery in embedded systems.
What package does the PTPS3840PH30DBVR come in?
The PTPS3840PH30DBVR is available in a 5-pin SOT-23 small outline low-profile package (JESD-30 code R-PDSO-G5), providing a very compact surface-mount footprint for space-constrained PCB layouts in portable and automotive electronics.
