Maximum supply current over temperature is a low 20µA, representing over 60 percent lower power as pared to the DS1233D. The IMP1233D 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-, 10- and 15-percent. 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 IMP1233D is designed with a open-drain output stage and operates over the extended industrial temperature range. Devices are available in pact surface mount SOT-223 packages. Other low power products in this family include the IMP1810/11/12/15/ 16/17 and IMP1233M.
