1 / 16 page © Semiconductor Components Industries, LLC, 2000 April, 2000 – Rev. 2 1 Publication Order Number: MC34161/D MC34161, MC33161 Universal Voltage Monitors The MC34161/MC33161 are universal voltage monitors intended for use in a wide variety of voltage sensing applications. These devices offer the circuit designer an economical solution for positive and negative voltage detection. The circuit consists of two comparator channels each with hysteresis, a unique Mode Select Input for channel programming, a pinned out 2.54 V reference, and two open collector outputs capable of sinking in excess of 10 mA. Each comparator channel can be configured as either inverting or noninverting by the Mode Select Input. This allows over, under, and window detection of positive and negative voltages. The minimum supply voltage needed for these devices to be fully functional is 2.0 V for positive voltage sensing and 4.0 V for negative voltage sensing. Applications include direct monitoring of positive and negative voltages used in appliance, automotive, consumer, and industrial equipment. • Unique Mode Select Input Allows Channel Programming • Over, Under, and Window Voltage Detection • Positive and Negative Voltage Detection • Fully Functional at 2.0 V for Positive Voltage Sensing and 4.0 V for Negative Voltage Sensing • Pinned Out 2.54 V Reference with Current Limit Protection • Low Standby Current • Open Collector Outputs for Enhanced Device Flexibility Simplified Block Diagram (Positive Voltage Window Detector Application) VCC 6 1 7 VS 2 3 + 1.27V + 1.27V + 2.8V + 0.6V + – 8 5 2.54V Reference – + – + + – 4 Device Package Shipping ORDERING INFORMATION MC34161D SO–8 98 Units/Rail MC34161P PDIP–8 MC33161D SO–8 PDIP–8 P SUFFIX CASE 626 1 8 http://onsemi.com 50 Units/Rail 98 Units/Rail SO–8 D SUFFIX CASE 751 1 8 MC33161DR2 SO–8 2500 Tape & Reel MC34161DR2 SO–8 2500 Tape & Reel MC33161P PDIP–8 50 Units/Rail MARKING DIAGRAMS x = 3 or 4 A = Assembly Location WL, L = Wafer Lot YY, Y = Year WW, W = Work Week PIN CONNECTIONS Vref Input 1 Input 2 Gnd VCC Mode Select Output 1 Output 2 1 2 3 4 8 7 6 5 (TOP VIEW) ALYW 3x161 1 8 AWL MC3x161P 1 8 YYWW |
