The Texas Instruments UCC3946PWTR is a microprocessor supervisor IC that provides essential reset and watchdog functions for embedded systems. It monitors a single supply voltage and asserts an active-low, push-pull reset output when the voltage drops below a programmable threshold. The device is designed to be resistant to glitches on the VDD line, ensuring stable operation.
Key features include a programmable reset threshold and reset period, along with a programmable watchdog timer. The reset signal remains asserted until the VDD voltage rises above the threshold and stays there for the specified reset period. The typical threshold voltage is 1.235V with 2% accuracy. The quiescent current is a low 0.01mA typical.
This supervisor IC is available in an 8-TSSOP package, suitable for surface mounting. The operating temperature range is 0°C to 70°C. The UCC3946PWTR is designed for applications requiring robust power-on reset and system monitoring capabilities, ensuring microprocessors operate within safe voltage limits.
