MCP121T-450E/TT Overview
There are 3 terminals connected to this power management, which makes it easy to mount. Power management is packaged in a Tape & Reel (TR) way. To assist you, this IC power includes 1 functions. There are 1 channels available on this supervisor, and each channel has a different function. In this IC management you will find TO-236-3, SC-59, SOT-23-3 functions for you to refer to. There are a lot of similarities between this IC management and other Simple Reset/Power-On Reset products. According to the specification, the package's peak reflow temperature is specified to be 260. Power management conducts at a voltage of 1. The power management is mounted by a Surface Mount-axis. It is possible to subcategorize this power ic as a Power Management Circuits chip. There are a total of 3 pins on power management. There are 3 pins on the supervisor. IC management can only work with a supply voltage of 1V volts. Voltage (Vsup) shouldn't exceed 5.5V volts in this PMIC. Surface Mount is the recommended mounting type. The supervisors should be set to the following temperature: -40°C~125°C TA. During operation, this power management system outputs Open Drain or Open Collector. For this power management, there is an 20μA volt supply current. If you want to search for similar IC managements of this manufacturer, you can always refer to MCP121, which is the base power ics number. Voltage supervisor can work with a supply temperature of 20μA at the most.
