UC1903L883B Product Details

UC1903L883B Overview


As you can see, this power management is mounted through 20 terminals. To assist you, this IC power includes 1 functions. There are 4 channels available on this supervisor, and each channel has a different function. When 15V is applied to the power ic, it conducts. It has a total of 20 pins that are attached to IC management. This power management has 20 pins. Supply voltage (Vsup) should be at least 8V for this power management. During this IC power, the maximum supply voltage (Vsup) should not exceed 40V volts. 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 15mA.
