Frequently Asked Questions
What is the primary function of the PTLV840MADL13DBVR?
The PTLV840MADL13DBVR is a low-voltage supervisor that monitors a supply rail and asserts a reset output when the monitored voltage falls below a programmable threshold. This ensures microcontrollers, FPGAs, and DSPs are held in a reset state during power-up and brownout conditions, preventing erroneous code execution or data corruption during unstable supply conditions.
Can the reset time delay be adjusted on the PTLV840MADL13DBVR?
Yes, the PTLV840MADL13DBVR features a programmable reset time delay that is set by an external timing capacitor connected to the delay pin. By selecting an appropriate capacitor value, designers can customize the reset assertion duration from a few milliseconds to hundreds of milliseconds, ensuring sufficient initialization time for the downstream microcontroller or FPGA after power rails stabilize.
Does the PTLV840MADL13DBVR have a manual reset input?
Yes, the PTLV840MADL13DBVR includes a manual reset (MR) input that allows an external signal — from a pushbutton, host processor GPIO, or test system — to force the reset output active regardless of the supply voltage status. This feature is useful for system debugging, factory test, and user-initiated resets in consumer and industrial electronics applications.
What package is the PTLV840MADL13DBVR available in?
The PTLV840MADL13DBVR is housed in a 5-pin SOT-23 package (JESD-30 code R-PDSO-G5), a small surface-mount package with 0.95mm pitch widely used for discrete components and small ICs. The SOT-23-5 package has a very small footprint suitable for space-constrained PCB designs in IoT, wearable, and handheld consumer device applications.
