MCP121T-270E/LB Product Details

MCP121T-270E/LB Overview


This voltage supervisor has a total of 3 mounting terminals that can be used for mounting. A Tape & Reel (TR) package is used to package the power management. In this IC power you will find 1 functions for you to refer to. A series of 1 channels can be found on this supervisor. Please refer to power management for SC-70, SOT-323 functions. There are a number of benefits that this PMIC has in common with other Simple Reset/Power-On Reset manage ics. The package peak reflow temperature is specified to be 260. IC management is possible to find a succession of 1 voltages that have been checked. Surface Mount is the one that mounts power management. The power management system can be categorized as a Power Management Circuits chip. In total, the power management has 3 pins in it. There are 3 pins on the power managment ic. In order for this PMIC to work correctly, the minimum supply voltage (Vsup) should be greater than 1V. The supply voltage (Vsup) should not exceed 5.5V volts in this IC power. The recommended mounting type is Surface Mount. The temperature of the supervisors should be set to this range: -40°C~125°C TA. As this power managment ic operates, it is able to produce an output voltage of Open Drain or Open Collector. As far as the supply current of the power management is concerned, it is 20μA. For similar manage ics search of the manufacturer, you can always refer to MCP121, the base PMIC number. A maximum supply temperature of 20μA can be used with this power management.
