Frequently Asked Questions
What voltages can the TPS386040RGPT monitor?
The TPS386040RGPT can monitor four independent voltage rails with an adjustable threshold as low as 0.404V maximum, making it suitable for supervising modern low-voltage supplies such as 1.0V, 1.8V, 2.5V, 3.3V, and 5V rails in multi-rail power systems.
Does the TPS386040RGPT include a watchdog timer?
Yes, the TPS386040RGPT integrates a watchdog timer (WDT) that monitors system firmware activity. If the microcontroller fails to service the watchdog within the configured timeout period, the device asserts a reset signal to recover the system, improving overall application reliability.
What package does the TPS386040RGPT come in, and what are its dimensions?
The TPS386040RGPT is packaged in a 20-pin QFN (VQFN) leadless package with a 0.16-inch square body, making it compact and suitable for high-density PCB layouts in space-constrained industrial and consumer electronic applications.
What are typical applications for the TPS386040RGPT?
Typical applications include multi-rail power supervision in embedded processors, FPGAs, DSPs, networking equipment, industrial PLCs, and automotive electronics where reliable voltage monitoring and automatic reset are essential for system safety and uptime.
Is the TPS386040RGPT RoHS compliant?
Yes, the TPS386040RGPT is RoHS compliant, as indicated by its Pbfree Code 'Yes' and JESD-609 Code 'e4', confirming that the device meets lead-free and halogen-free environmental standards required for modern electronics manufacturing.
