RS809 Supply Voltage Supervisor with Reset Circuits
■The RS809 microprocessor (μP) supervisory circuits reduce the complexity and number of components required to monitor power-supply and battery function in μP systems. This device significantly improves system reliability and accuracy compared to separate ICs or discrete components.
■These circuits perform a single function: they assert a reset signal whenever the V-CC supply voltage declines below a preset threshold, keeping it asserted for at least 200ms after V-CC has risen above the reset threshold. Reset thresholds suitable for operation with a variety of supply voltages are available.
■The RS809 have push-pull outputs. The RS809 have an active-low RESET output. The reset comparator is designed to ignore fast transients on V-CC, and the outputs are guaranteed to be in the correct logic state for V-CC down to 1.0V.
■Low supply current makes the RS809 ideal for use in portable equipment. The RS809is available in Green SOT23 package. It operates over an ambient temperature range of -40°C to +125°C.
