NCP305LSQ29T1G Overview
There are 4 mounting terminals on the voltage supervisor, each of which has a different function. Packaging is in the form of a Tape & Reel (TR). For your reference, this IC power includes a list of 1 functions. There are a total of 1 channels on this supervisor, and they are arranged in a series. In this IC management you will find SC-82A, SOT-343 functions for you to refer to. There are a lot of similarities between this IC power and other Simple Reset/Power-On Reset products. Specifies a reflow peak temperature of 260 for the package during reflow. When 1.5V is applied to the power ic, it conducts. In a 1 supply voltage, the PMIC chip conducts. Surface Mount mounts IC management. A IC power such as this can be classified as a Power Management Circuits power management system. Taking into account all of the pins, this power management has a total of 4. There are 4 pins on the power managment ic. In order for this IC power to function, the supply voltage (Vsup) cannot be less than 800mV. During this IC power, the maximum supply voltage (Vsup) should not exceed 10V volts. Power management recommends the Surface Mount mounting type. The supervisors should be set to the following temperature: -40°C~85°C TA. Power management has an output of Open Drain or Open Collector during operation. Supplied with a operating current of 1μA, this PMIC is capable of fully function as specified. For similar manage ics search of the manufacturer, you can always refer to NCP305, the base PMIC number. At most, voltage supervisor can operate at a supply temperature of 3.5μA.
