Maximum supply current over temperature is a low 20µA, representing 60 percent lower power as pared to the DS1233M. The IMP1233M issues an active LOW reset signal whenever the monitored supply is out-of-tolerance. A precision reference and parator circuit monitor power supply (VCC) level. Tolerance level options are 5- and 10-percent for a 5V power supply. The tolerance is 15-percent for the 3.3V, IMP1233M. When an out-of-tolerance condition is detected, an internal power-fail signal is generated which forces an active LOW reset signal. After VCC returns to an in-tolerance condition, the reset signal remains active for 350ms to allow the power supply and system microprocessor to stabilize. The IMP1233M is designed with a open-drain output stage and operates over the extended industrial temperature range. Devices are available in the pact surface mount SO-8 package. Other low power products in this family include the IMP1810/11/12/15/ 16/17 and IMP1233D.
