ASM1834 Datasheet | Alliance Semiconductor

.. April 2005 rev 1.3 ASM1834/A/D Dual 5V and 3.3V µP Power Supply Supervisor with Manual Reset All devices operate over the extended industrial temperature range. Devices are available in 8-pin DIP, surface mount 8-pin SO and 8-Pin MicroSO packages. Die are also available. General Description The ASM1834 supervisors simultaneously monitor both 3.3V and 5V power sources and generate reset signals when either supply is out of tolerance. When an out-of-tolerance condition is detected, the output-reset signal of the affected supply bees active and resets the system microprocessor/ microcontroller. On power-up and after the supply voltage returns to an in-tolerance...
