MAX6443US44L Product Details

MAX6443US44L Overview


It is mounted through 4 terminals on the power management. There are 1 functions included in this PMIC so that you can refer to them. It is possible to find on this power management a series of 1 channels. There are SOT-143 functions included in this PMIC so that you can refer to them. IC management is specified that the package peak reflow temperature should be 260. During operation, the power ic is supplied with a voltage of 3.6V. Using Surface Mount, IC management is mounted. As a subcategory, this PMIC chip can be categorized as Power Management Circuits. In total, IC powers are 4 pins on the board. 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.
