                                                HPA02135DBTR Overview
For the 38-TFSOP (0.173, 4.40mm Width) package, it is appropriate. IC POWER SUPPLY MANAGEMENT CIRCUIT is the device's analog IC. There are 1 channels available. Currently, there are 38 pins on it. It's packaged in a Tape & Reel (TR) case. Surface Mount is positioned in the way of this part. It can deliver the functions listed in Multi-Function Controller. To best deliver its performance, the part should be operated at a temperature of -40°C~85°C TA. In this part, the battery chemistry includes Lithium Ion/Polymer. It is imperative to keep this device set to 14V at all times. There is a HPA02135 family at the core of it. Upon reaching 25V, the maximum supply voltage (Vsup) can be applied. A voltage greater than 4.5V (Vsup) must be required for a power supply. In this case, Impedance Track? represents the series number of the device.
