MAX6421US42 Product Details

MAX6421US42 Overview


There are SOT-143 functions included in this PMIC so that you can refer to them. Using Surface Mount, IC management is mounted. 4 pins make up the power management. In order for this PMIC to work correctly, the minimum supply voltage (Vsup) should be greater than 1V. Voltage (Vsup) shouldn't exceed 5.5V volts in this PMIC. It is also possible to use other types of IC, such as POWER SUPPLY SUPPORT CIRCUIT, in this supervisor.
