   产品概述 返回TOPhRg嘉泰姆

The CXDR7590 is a cost-effective system supervisor Integrated Circuit (IC) designed to monitor VCC in digital and mixed signal systems and provide a warning signal when the system power supply is out of working range, and a reset signal to the host processor when necessary. No external components are required. The CXDR7590 also provides a manual reset input. The reset output is driven active within 20μsec of VCC falling through the reset voltage threshold. Reset is maintained active after VCC rises above the RESET threshold. The CXDR7590 has an active-low RESET output. The output of the CXDR7588 is guaranteed valid down to VCC=1V. The CXDR7590 is characterized for operation from -40o C to 125o C, junction temperature. The CXDR7590 is optimized to reject fast transient glitches on the VCC line. Low supply current of 7μA (VCC=3.3V) makes these devices suitable for battery powered applications. The output voltages range from 1.7V to 4.5V in 100mV increments. Standard voltage versions are 2.30, 2.63, 2.93, 3.08, 4.0, 4.38, and 4.63V.
