MCP121-450E/TO Overview
A total of 3 terminals are used to mount this power management. This power ic is packaged in a way that looks like a Bulk. Please refer to this PMIC for 1 functions. A series of 1 channels can be found on this supervisor. IC management is packaged as a TO-226-3, TO-92-3 (TO-226AA) package. There are a lot of similarities between this IC management and other Simple Reset/Power-On Reset products. IC management is possible to find a succession of 1 voltages that have been checked. Using Through Hole, IC management is mounted. In this case, this PMIC chip can be sub-categorized as a Power Management Circuits chip. In total, IC powers are 3 pins on the board. Power managment ic pin count is 3. There should be a minimum voltage supply (Vsup) of 1V for this PMIC. The supply voltage (Vsup) should not exceed 5.5V volts in this IC power. Power management' mounting is recommended to be done with the Through Hole type of mounting. This range of temperature should be set for the supervisors: -40°C~125°C TA. During normal operation, this power managment ic can generate Open Drain or Open Collector of output voltage. For this power management, there is an 20μA volt supply current. To find similar IC managements from the manufacturer, you can always search by MCP121. A maximum supply temperature of 20μA can be used with this power management.
