DS1817R-20-U+ Product Details

DS1817R-20-U+ Overview


A total of 3 terminals are used to mount this power management. Please refer to this PMIC for 1 functions. There are a total of 1 channels on this supervisor, and they are arranged in a series. Please refer to power management for SOT-23 functions. During the reflow process, a peak temperature of 260 is specified for the package. Manage ics operate at 3.3V supply voltages. The power management is mounted by Surface Mount. There is a subcategory of this power ic known as Power Management Circuits. There are a total of 3 pins on power management. Power managment ic pin count is 3. Normally, the supply voltage (Vsup) for this PMIC should not be lower than 0V. There should be no more than 5.5V volts of supply voltage (Vsup) in this power management. There are also other types of integrated circuits included in the supervisor, like POWER SUPPLY SUPPORT CIRCUIT. A maximum supply temperature of 35μA can be used with this power management.
