CAT1640WI-28 Product Details

CAT1640WI-28 Overview


It is mounted through 8 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. IC management is specified that the package peak reflow temperature should be 260. During operation, the power ic is supplied with a voltage of 3.3V. During operation, the power ic is supplied with a voltage of 1. In total, IC powers are 8 pins on the board. 8 pins make up the power management. In order for this PMIC to work correctly, the minimum supply voltage (Vsup) should be greater than 3V. Voltage (Vsup) shouldn't exceed 5.5V volts in this PMIC. As far as the supply current of the power management is concerned, it is 3mA. It is also possible to use other types of IC, such as POWER SUPPLY SUPPORT CIRCUIT, in this supervisor.
