MC33064 Datasheet | onsemi

Undervoltage Sensing Circuit MC34064, MC33064, NCV33064 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 parator 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 m A, 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. Features - Trimmed- In- Package Temperature pensated Reference - parator Threshold of 4.6 V at 25C - Precise parator Thresholds Guaranteed Over Temperature - parator Hysteresis Prevents Erratic Reset - Reset Output Capable of Sinking in Excess of 10 m A - Internal Clamp Diode for Discharging Delay Capacitor - Guaranteed Reset Operation with 1.0 V Input - Low Standby Current - Economical TO- 92, TSOP- 5, SOIC- 8 and Micro8 Surface Mount Packages - NCV Prefix for Automotive and Other Applications Requiring Site and Control Changes - These Devices are Pb- Free and are Ro HS pliant Input Reset DATA SHEET .onsemi. 8 1 8 1 5 1 SOIC- 8 D SUFFIX CASE 751 Micro8 DM SUFFIX CASE 846A TSOP- 5 SN SUFFIX CASE 483 Pin 1.
