Texas Instruments TPS3847 18V 380nA Voltage Monitor

Texas Instruments TPS3847 18V 380nA Voltage Monitor is a wide operating voltage, an ultra-low current device that monitors the voltage at the supply pin. The device asserts an active-low reset signal whenever the VCC supply voltage drops below the factory-trimmed reset threshold voltage. The reset output remains asserted for 20ms (max) after the VCC voltage rises above the threshold voltage. The ultra-low current consumption of 380nA combined with 18V capability makes the TPS3847 ideal for use in low-power and portable applications. The TPS3847 features precision, factory-trimmed threshold voltages, and extremely low-power operation. The Texas Instruments TPS3847 is available in an industry-standard 5-pin SOT-23 package.
