DATA SHEET www.onsemi.com Undervoltage Sensing Circuit 1 SOIC−8 D SUFFIX CASE 751 1 Micro8 DM SUFFIX CASE 846A 1 TSOP−5 SN SUFFIX CASE 483 8 MC34064, MC33064, NCV33064 8 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 Micro8 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. 5 Pin 1. 2. 3. 4. 5.
