TS831-4IZ Product Details

TS831-4IZ Overview


There are 3 mounting terminals on the voltage supervisor, each of which has a different function. It is packaged with Bulk. As a reference, this IC management includes 1 functions for your convenience. There are 1 channels on this power managment ic that can be found in a series. IC management is packaged as a TO-226-3, TO-92-3 (TO-226AA) package. There are a lot of similarities between this IC power and other Simple Reset/Power-On Reset products. IC management conducts at a voltage of 5V. IC management conducts in a 1-voltage supply. Power management is included in the Through Hole mount. Power Management Circuits is a subcategory of this PMIC chip. In total, it has 3 pins on IC management. This power management has 3 pins. A voltage (Vsup) that doesn't fall below 1V as the minimum supply voltage (Vsup) should be applied to this IC power in order to ensure its proper operation. The supply voltage (Vsup) should not exceed 5.5V volts in this IC power. In this case, Through Hole is the recommended mounting type. You should set the supervisor's temperature during -40°C~125°C TA . The output voltage of this power managment ic during operation is Open Drain or Open Collector. It is estimated that the voltage supervisor's supply current is 12μA. There are other features such as RESET THRESHOLD VOLTAGE IS 4.50V to name a few. To find similar IC managements from the manufacturer, you can always search by TS831. A maximum supply temperature of 12μA can be used with this power management.
