MC3464, MC3364, NCV3364 Undervoltage Sensing Circuit The MC3464 is an undervoltage sensing circuit specifically designed for use as a reset controller in microprocessorbased systems.

1 MC3464, MC3364, NCV3364 Undervoltage Sensing Circuit The MC3464 is an undervoltage sensing circuit specifically designed for use as a reset controller in microprocessorbased systems. It offers the designer an economical solution for low voltage detection with a single external resistor. The MC3464 features a trimmedinpackage bandgap reference, and a comparator with precise thresholds and built in hysteresis to prevent erratic reset operation. The open collector reset output is capable of sinking in excess of ma, and operation is guaranteed down to. V input with low standby current. The MC devices are packaged in 3pin TO 92, micro size TSOP5, pin SOIC and Micro surface mount packages. The NCV device is packaged in SOIC and TO92. Applications include direct monitoring of the 5. V MPU/logic power supply used in appliance, automotive, consumer and industrial equipment. Features TrimmedInPackage Temperature Compensated Reference Comparator Threshold of 4.6 V at 25 C Precise Comparator Thresholds Guaranteed Over Temperature Comparator Hysteresis Prevents Erratic Output Capable of Sinking in Excess of ma Internal Clamp Diode for Discharging Delay Capacitor Guaranteed Operation with.
