BU4938F-TR Product Details

BU4938F-TR Overview


There are 4 terminals on this power management that allow it to be mounted. Packaged in a Tape & Reel (TR)-shape, IC management comes with a number of features. 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-82 functions included in this PMIC so that you can refer to them. There are a number of benefits that this PMIC has in common with other Simple Reset/Power-On Reset manage ics. There is a voltage supply of 2.4V for the PMIC chip, and the chip conducts at that voltage. During operation, the power ic is supplied with a voltage of 1. Power management is included in the Surface Mount mount. There is a subcategory called Power Management Circuits for this power management. Power management has a total of 4 pins. Power managment ic pin count is 4. It is recommended that the minimum supply voltage (Vsup) for this IC management should not be less than 700mV volts. Voltage (Vsup) shouldn't exceed 7V volts in this PMIC. In this case, Surface Mount is the recommended mounting type. Temperature setting for the supervisors should be -40°C~125°C TA. When this power management system is in operation, it produces an output voltage of Push-Pull, Totem Pole. The supervisor's supply current is specified to 550nA. For similar manage ics search of the manufacturer, you can always refer to BU4938, the base PMIC number. It requires 2.5/5V watts of power to operate this voltage supervisor. Voltage supervisor can work with a supply temperature of 1.58μA at the most.
