CAT1641WI-28 Product Details

CAT1641WI-28 Overview


As you can see, this power management is mounted through 8 terminals. To assist you, this IC power includes 1 functions. There are 1 channels available on this supervisor, and each channel has a different function. According to the specification, the package's peak reflow temperature is specified to be 260. When 3.3V is applied to the power ic, it conducts. When 1 is applied to the power ic, it conducts. The mount is attached to Surface Mount. It has a total of 8 pins that are attached to IC management. This power management has 8 pins. Supply voltage (Vsup) should be at least 3V for this power management. During this IC power, the maximum supply voltage (Vsup) should not exceed 5.5V volts. There is a 3mA supply current present in the power management. It also contains ICs of other kinds, such as POWER SUPPLY SUPPORT CIRCUIT, which are included in the power management. If you want to work with PMIC chip, you will need to supply PMIC chip with a temperature at least of 3mA.
