                                                BQ28550DRZR-R1 Overview
This package corresponds to 12-VFDFN Exposed Pad. The analog IC in this device is POWER SUPPLY SUPPORT CIRCUIT. There are currently 1 channels available. The total number of pins is 12. The package contains a Cut Tape (CT) case. To mount this part, use Surface Mount. This part is mounted in the way of Surface Mount. As far as the Multi-Function Controller functions are concerned, it can be delivered. When a part is operated at -40°C~85°C TA, its performance will be optimal. Chemistries for this part are Lithium-Ion. Keep in mind that this device should be set to 3.6V at all times. It is based on BQ28550 family. Using this device, you can discover a value of OVERCHARGE DETECTION IS 4.25V. There is a maximum supply voltage (Vsup) of 5.5V. Ideally, Vsup (supply voltage) should be greater than 2.45V. 20mA volts of supply current power it.
