Product Summary

The DS1834A is a Dual EconoResets monitor. The three vital system conditions of it are 5-volt supply, 3.3volt supply, and an external override. Lastly, the DS1834A supports an external reset via an internally debounced pushbutton input. When the pushbutton is pulled low both resets will be asserted for approximately 350 ms after the pushbutton is released.

Parametrics

DS1834A absolute maximum ratings: (1)Voltage on VIN Pin Relative to Ground: -0.5V to +7.0V; (2)Voltage on RST (5V) Pin Relative to Ground: -0.5V to +0.5VIN + 0.5V; (3)Voltage on RST (3.3V) Pin Relative to Ground: -0.5V to +3.3VIN + 0.5V; (4)Voltage on Pin Relative to Ground: -0.5 to the greater of 0.5VIN + 0.5V or 3VIN + 0.5V; (5)Operating Temperature: -40 to +85℃; (6)Storage Temperature: -55 to +125℃; (7)Soldering Temperature: 260℃ for 10 seconds.

Features

DS1834A features: (1)5V power-on reset; (2)3.3V power-on reset; (3)Internal power is drawn from higher of either the 5VIN input or the 3.3VIN input; (4)Excellent for systems designed to operate with dual power supplies; (5)Asserts resets during power transients; (6)Pushbutton reset input for system override; (7)Maintains reset for 350 ms after VCC returns to an in-tolerance condition; (8)Reduces need for discrete components; (9)Precision temperature-compensated voltage reference and voltage sensor; (10)8-pin DIP, 8-pin SOIC, and 8-pin μ-SOP available; (11)CMOS output for low current operation on the DS1834; (12)Operating temperature of -40℃ to +85℃.
