Low Voltage Detector MD70XX SERIES (NMOS/CMOS) General Description The MD70XX series is a set of three-terminal low power voltage detectors implemented in CMOS technology. Each voltage detector in the series detects a particular fixed voltage ranging from 1.2V to 7V. The voltage detectors consist of a high-precision and low power consumption standard voltage source, a comparator, hysteresis circuit, and an output driver. CMOS technology ensures low power consumption. Although designed primarily as fixed voltage detectors, these devices can be used with external components to detect user specified threshold voltages Features Applications · Low power consumption · Low temperature coefficient · Built-in high-stability reference source · Open drain types: NMOS: MD70XX CMOS: 70XXC · Built-in hysteresis characteristic · TO-92 package · SOT-89 package · SOT-23-3/5 package · SSOT-24 package · Battery checkers · Level selectors · Power failure detectors · Microcomputer reset · Battery memory backup · Non-volatile RAM signal storage protectors Absolute Maximum Ratings Supply Voltage.................... ............. -0.3V to 18V Output Voltage ..................VSS-0.3V to VDD+0.3V Storage Temperature.......................-50℃to 125℃ Operating Temperature..............-40℃to 85℃ Output Current......................... 10mA Power Consumption: SOT89-3 500mW TO-92 300mW SOT23-/5 250mW SSOT-24 250mW Note: These are stress ratings only.
