CAT809SEUR-T Product Details

CAT809SEUR-T 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-23-3 functions. During the reflow process, a peak temperature of 240 is specified for the package. Manage ics operate at 3.3V supply voltages. The power management is mounted by Surface Mount. 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 1.2V. There should be no more than 5.5V volts of supply voltage (Vsup) in this power management. It is estimated that the voltage supervisor's supply current is 6μA. There are also other types of integrated circuits included in the supervisor, like POWER SUPPLY SUPPORT CIRCUIT. With 1 elements, this supervisor has been used extensively in all application areas.
