UCC2946 UCC3946 SLUS247F − APRIL 1997 − REVISED NOVEMBER 2007 MICROPROCESSOR SUPERVISOR WITH WATCHDOG TIMER FEATURES D Fully Programmable Reset Threshold D Fully Programmable Reset Period D Fully Programmable Watchdog Period D 2% Accurate Reset Threshold D Input Voltage Down to 2 V D Input 18-µA Maximum Input Current D Reset Valid Down to 1 V DESCRIPTION The UCCx946 is designed to provide accurate microprocessor supervision, including reset and watchdog functions. During power up, the device asserts a reset signal RES with VDD as low as 1 V. The reset signal remains asserted until the VDD voltage rises and remains above the reset threshold for the reset period. Both reset threshold and reset period are programmable by the user. The UCCx946 is also resistant to glitches on the VDD line.
