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. These devices are packaged in 3-pin TO-226AA, 8-pin SO–8 and Micro–8 surface mount packages. Applications include direct monitoring of the 5.0 V MPU/logic power supply used in appliance, automotive, consumer and industrial equipment. • Trimmed-In-Package Temperature Compensated Reference • Comparator Threshold of 4.6 V at 25°C • Precise Comparator Thresholds Guaranteed Over Temperature • Comparator Hysteresis Prevents Erratic Reset • Reset Output Capable of Sinking in Excess of 10 mA • Internal Clamp Diode for Discharging Delay Capacitor • Guaranteed Reset Operation with 1.0 V Input • Low Standby Current • Economical TO–226AA, SO–8 and Micro–8 Surface Mount Packages Representative Block Diagram 1.2 Vref 2 (2) 1 (1) 3 (4) Reset Gnd Input = Sink Only Positive True Logic Pin numbers adjacent to terminals are for the 3–pin TO–226AA package. Pin numbers in parenthesis are for the 8–lead packages. This device contains 21 active transistors. © Motorola, Inc. 1996 Rev 2 |
