STM1818RWX7F Overview


As you can see, this power management is mounted through 3 terminals. There is a Tape & Reel (TR)-packaging method applied to IC management. In this IC power you will find 1 functions for you to refer to. This power managment ic consists of 1 channels, each of which can be used independently. As a reference, this IC power includes TO-236-3, SC-59, SOT-23-3 functions for your convenience. There are a lot of similarities between this IC power and other Simple Reset/Power-On Reset products. According to the specification, the package's peak reflow temperature is specified to be 260. When 3.6V is applied to the power ic, it conducts. When 1 is applied to the power ic, it conducts. The mount is provided by Surface Mount. As a subcategory, this PMIC chip can be categorized as Power Management Circuits. In total, it has 3 pins on IC management. 3 pins are on the supervisor. IC management can only work with a supply voltage of 1.2V volts. The maximum supply voltage (Vsup) in this PMIC should not exceed 5.5V volts. In this case, Surface Mount is the recommended mounting type. The supervisors should be set to the following temperature: -40°C~105°C TA. As this power managment ic operates, it is able to produce an output voltage of Open Drain, Bidirectional. In order to maintain a stable supply current for the power management, 16μA is the recommended value. A similar IC managements number of the manufacturer can always be found by using STM1818, the base power ics number. The maximum supply temperature is 16μA.
