Overview of UCC3946DTR

Designed for maximum precision and reliability, the UCC3946DTR is specifically engineered to ensure accurate microprocessor supervision, reset functions, and watchdog capabilities. Its reset signal (RES) is assertive during power up, holding until the VDD voltage surpasses the user-programmable reset threshold for a specific reset period. The device is resilient to VDD line glitches, with stringent requirements for generating a reset signal after RES deassertion. Equipped with a watchdog input (WDI), the UCC3946DTR allows for watchdog functions to be tied to a microprocessor's I/O line, programmable for a set watchdog period, and automatically disabled during reset conditions. Furthermore, the availability of the UCC3946DTR in 8-pin SOIC(D), 8-pin PDIP (N), and 8-pin TSSOP(PW) packages optimizes board space and enhances ease of integration, making it a versatile and convenient solution for microprocessor supervision requirements
