NCV33064D-5R2G

MC34064, MC33064, NCV33064 Undervoltage Sensing Circuit The MC34064 is an undervoltage sensing circuit specifically designed for use as a reset controller in microprocessor−based systems. It offers the designer an economical solution for low voltage detection with a single external resistor. The MC34064 features a trimmed−in−package 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 10 mA, and operation is guaranteed down to 1.0 V input with low standby current. The MC devices are packaged in 3−pin TO-92, micro size TSOP−5, 8−pin SOIC−8 and Micro8t surface mount packages. The NCV device is packaged in SOIC−8 and TO−92. Applications include direct monitoring of the 5.0 V MPU/logic power supply used in appliance, automotive, consumer and industrial equipment. Features http://onsemi.com TO−92 P SUFFIX CASE 29 Pin 1.

Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied, damage may occur and reliability may be affected. 1. ESD data available upon request.
