DS1819AR-20-U Overview
This voltage supervisor has a total of 5 mounting terminals that can be used for mounting. A Tube package is used to package the power management. Please find attached 1 functions for your reference in this IC power. On this supervisor, there is a series of 1 channels that can be found. There are SC-74A, SOT-753 functions included in this PMIC so that you can refer to them. There are a lot of similarities between this IC management and other Simple Reset/Power-On Reset products. IC management conducts at a voltage of 3.3V. A supply voltage of 1 is used to conduct the PMIC chip. The power management is mounted by a Surface Mount-axis. As a subcategory, this PMIC chip can be categorized as Power Management Circuits. It has a total of 5 pins that are attached to IC management. The pins of the power management system count 5. IC management can only work with a supply voltage of 1V volts. The maximum supply voltage (Vsup) in this PMIC should not exceed 5.5V volts. A Surface Mount mounting type is recommended. This range of temperature should be set for the supervisors: -40°C~85°C TA. During operation, this power management system outputs Push-Pull, Totem Pole. For this power management, there is an 12μA volt supply current. You can always use DS1819, the base supervisor number, to search for similar PMICs of the manufacturer. At the most, voltage supervisor can work with a supply temperature of 12μA. It is one of the well-known MicroMonitor? series power ic line.
