BU4941F-TR Product Details

BU4941F-TR Overview


As you can see, this power management is mounted through 4 terminals. There is a Tape & Reel (TR)-packaging method applied to IC management. In this PMIC, you can find 1 functions for your reference. There are a total of 1 channels on this supervisor, and they are arranged in a series. In this PMIC, you can find SC-82 functions for your reference. There are a lot of similarities between this IC management and other Simple Reset/Power-On Reset products. A supply voltage of 2.4V is used to conduct the PMIC chip. During operation, the power ic is supplied with a voltage of 1. By Surface Mount, IC management has been mounted. The power management system can be categorized as a Power Management Circuits chip. In total, IC powers are 4 pins on the board. Pin count of the power management is 4. Supply voltage (Vsup) should be at least 700mV for this power management. During this IC power, the maximum supply voltage (Vsup) should not exceed 7V volts. Mounting type Surface Mount is recommended. It is recommended that the supervisor be set to this temperature: -40°C~125°C TA. During operation, this power management system outputs Push-Pull, Totem Pole. The supervisor's supply current is specified to 550nA. It is always advisable to use BU4941, the base supervisor number, when searching for similar PMICs from the manufacturer. The voltage supervisor requires a power source of 2.5/5V volts in order to work correctly. The maximum supply temperature that PMIC chip can work with is 1.58μA.
