... V BOOST TSOURCE point. The top and bottom gate drivers in the LT1160 each utilize two gate connections gate drive pin, which provides the turn on and turn off currents through an optional series gate resistor, and 2) a gate feedback pin which connects directly to the gate to monitor the gate-to-source voltage ...

... If gate decoupling resistors are used the corresponding gate feedback pin can be connected to any one of the gates as shown in Figure 1. Driving multiple MOSFETs in parallel may restrict the operating frequency to prevent overdissipation in the DS(ON) LT1160 (see the following Gate Charge and Driver Dissi- pation). vs tempera- DS(ON and the A ...

... U U APPLICATIONS INFORMATION The actual increase in supply current is slightly higher due to LT1160 switching losses and the fact that the gates are being charged to more than 10V. Supply Current vs Input Frequency is given in the Typical Performance Characteristics. The LT1160 junction temperature can be estimated by using the equations given in Note 2 of the Electrical Characteristics ...

... Figure 2. Adding Synchronous Switching to a Step-Down Switching Regulator Motor Drive Applications In applications where rotation is always in the same direction, a single LT1160 controlling a half-bridge can be used to drive a DC motor. One end of the motor may be connected either to supply or to ground as seen on Figure 3. A motor in this configuration is controlled by its inputs which give three alternatives: run, free running stop (coast- ing) and fast stop (“ ...
