Processor Supervisor 5V 1.2V to 5.5V 4-Pin(3+Tab) SOT-223

The DS1833 is pin-compatible with the DS1233 and similar in function to the DS1233D but with an active high reset. It is intended for 5V systems that require a 350ms hold on active high reset for system stabilization. The DS1833 monitors power supplies and automatically restarts the processor when operational safety thresholds are breached. It is designed with CMOS outputs and is capable of maintaining a valid output on the active high reset to 1.2V with an internal 5kO pull-up resistor. On power-up, the DS1833 holds reset for 350ms to allow the system to stabilize. With a variety of features that can target a specific application, EconoResets provide simple and cost-effective CPU monitoring solutions.
