STM1811LWX7F Overview


As far as the mounting terminals of this voltage supervisor are concerned, it has 3 in total. In terms of packaging, power management follows the Tape & Reel (TR) model. As a reference, this IC management includes 1 functions for your convenience. There are 1 channels available on this supervisor, and each channel has a different function. IC management is packaged as a TO-236-3, SC-59, SOT-23-3 package. There are a lot of similarities between this IC management and other Simple Reset/Power-On Reset products. There is a specification for the peak reflow temperature of the package to be 260. The supervisor is always powered by a 3.6V volt supply. A supply voltage of 1 is used to conduct the PMIC chip. The mount is provided by Surface Mount. As a subcategory, this PMIC chip can be categorized as Power Management Circuits. Taking into account all of the pins, this power management has a total of 3. There are 3 pins on the supervisor. IC management can only work with a supply voltage of 1.2V volts. It is recommended that the maximum supply voltage (Vsup) in this IC power be no more than 5.5V volts. Power management recommends the Surface Mount mounting type. We recommend setting the supervisors to -40°C~105°C TA degrees. There is an output voltage of Open Drain or Open Collector from this supervisor when it is operating. The supervisor's supply current is specified to 4μA. To find similar IC managements from the manufacturer, you can always search by STM1811. A maximum supply temperature of 16μA can be used.
