4-Pin μP Voltage Monitors with Manual Reset Input CXDR75103 ideal for use in portable equipment These circuits perform a single function: they assert a reset signal whenever the VCC supply voltage

   产品概述 返回TOPt7t嘉泰姆

These circuits perform a single function: they assert a reset signal whenever the VCC supply voltage declines below a preset threshold, keeping it asserted for at least 220ms after VCC has risen above the reset threshold. Reset thresholds suitable for operation with a variety of supply voltages are available. The CXDR75103 have a push-pull and active-low RESET output. The reset comparator is designed to ignore fast transients on VCC, and the outputs are guaranteed to be in the correct logic state for VCC down to 1V. Low supply current makes the CXDR75103 ideal for use in portable equipment. The CXDR75103 are available in a SOT-143 packages.The CXDR75103 are microprocessor (μP) supervisory circuits used to monitor the power supplies in μP and digital systems. They provide excellent circuit reliability and low cost by eliminating external components and adjustments when used with +5V, +3.3V, +3.0V- powered circuits. The CXDR75103 also provides a debounced manual reset input
