MAX821UUS+T Product Details

MAX821UUS+T Overview


This voltage supervisor has a total of 4 mounting terminals that can be used for mounting. There is a Tape & Reel (TR)-packaging method applied to IC management. To assist you, this IC power includes 1 functions. A series of 1 channels can be found on this supervisor. In this IC management you will find TO-253-4, TO-253AA functions for you to refer to. Compared to other Simple Reset/Power-On Reset products, this PMIC has a lot of benefits to offer. The package peak reflow temperature is specified to be 260. There is a voltage supply of 1 for the PMIC chip, and the chip conducts at that voltage. Using Surface Mount, IC management is mounted. It is possible to subcategorize this power ic as a Power Management Circuits chip. In total, it has 4 pins on IC management. The pins of the power management system count 4. I should note that the minimum supply voltage (Vsup) for this IC management should be at least 1V, which is the minimum supply voltage that should be applied. The maximum supply voltage (Vsup) is not to exceed 5.5V volts in this IC management. Surface Mount is the recommended mounting type. The temperature of the supervisors should be set to this range: -40°C~125°C TA. There is an output voltage of Push-Pull, Totem Pole from this supervisor when it is operating. For this power management, there is an 5.5μA volt supply current. There are other features such as DETECTION THRESHOLD VOLTAGE IS 2.78 V to name a few. For similar manage ics search of the manufacturer, you can always refer to MAX821, the base PMIC number. At the most, voltage supervisor can work with a supply temperature of 5.5μA.
