UCC2946PWTR Description

Short technical summary and product information.

The UCC2946PWTR from Texas Instruments is a microprocessor supervisor IC designed to provide accurate supervision, including reset and watchdog functions. It features a fully programmable reset threshold and reset period, along with a programmable watchdog period. The device can assert a reset signal with VDD as low as 1V, remaining asserted until the voltage rises above the reset threshold for the specified reset period. It is also resistant to glitches on the VDD line.

 

Key electrical specifications include an input voltage down to 1V, a maximum input current of 18µA, and a 2% accurate reset threshold. The operating temperature range is -40°C to 85°C. The UCC2946PWTR comes in an 8-TSSOP package and is designed for surface mount.

 

This supervisor IC is suitable for applications requiring reliable monitoring of microprocessor power supply and operation. Its programmable features allow for customization to specific system requirements, ensuring robust performance and preventing system malfunctions due to voltage drops or watchdog timeouts.
