CAT8836:NanoPower Supervisory Circuits
The CAT8836 is a voltage supervisory circuit intended to provide circuit initialization and start-up timing for DSPs and other processor-based systems. When system power comes on, CAT8836's output once the supply voltage VDD becomes higher than 1.1 V. Thereafter, the supervisory circuit monitors VDD and keeps the output active as long as VDD remains below the threshold voltage of VTH. After VDD exceeds the monitoring threshold an internal timer delays the return of the output to the inactive state (high) to ensure proper system reset. The duration of this reset delay is controlled by the CT input. When CT is connected to GND the reset delay is 10 ms, typical, in duration and when connected to VDD, the delay time is typically 200 ms. Whenever the supply voltage drops below the monitoring threshold voltage VTH, the output becomes active (low) again.
