IMP1834D General Description

The IMP1834 supervisors simultaneously monitor both 3.3V and 5V power sources and issue 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 becomes active and resets the system microprocessor/ microcontroller. On power-up and after the supply voltage returns to an in-tolerance condition, the reset signal remains active for approximately 350ms. This allows the power supply and system microprocessor to stabilize.

The IMP1834 supervisors are pin-compatible with devices from Dallas Semiconductor and require up to 40% less current. Tolerance levels are independently selectable for both supplies. Tolerance options are 5- and 10-percent for the 5V supply and for the 3.3V supply, 10- and 20-percent.

The IMP1834 and IMP1834D have push-pull reset output stages. The IMP1834A active LOW reset outputs are open drain devices that can both be connected to either 5 volt or 3.3 volt supply. The IMP1834 and IMP1834A have active LOW reset outputs. The IMP1834D has active HIGH reset outputs.

All devices can issue reset signals through an internally debounced pushbutton reset input that affects both reset outputs.

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.
