LBNB ma LOAD SWITH FEATURING OMPLEMENTARY BIPOLAR TRANSISTORS NEW PRODUT General Description LMNB is best suited for applications where the load needs to be turned on and off using control circuits like micro-controllers, comparators etc. particularly at a point of load. It features a discrete PNP pass transistor with stable V ce_sat which does not depend on the input voltage and can support maximum continuous current of ma up to 2 (see fig. ). It also contains a discrete NPN that can be used as a control. The component devices can be used as a part of a circuit or as standalone discrete devices.

Application Details Vin EQ Q Q PNP Vout NEW PRODUT PNP Transistor and NPN Transistor integrated as one in LBNB can be used as a discrete entity for general purpose applications or as a part of a circuit to function as a Load Switch. When it is used as the latter as shown in Example ircuit Schematic, various input voltage sources can be used as long as they do not exceed the maximum rating of the device. These devices are designed to deliver continuous output load current up to maximum of ma. The use of the NPN as a switch eliminates the need for higher current required to overcome the gate charge in the event an N-MOSFET is used. are must be taken for higher levels of dissipation while designing for higher load conditions. These devices provide power on demand and also consume less space. It mainly helps in optimizing power usage, thereby conserving battery life in a controlled load system like portable battery powered applications.
