# Mosfet and mosfet driver question

I need to drive a single n channel mosfet. To do that, I choose LTC1154 Mosfet driver. The first question of mine, power of the driver is supplied by 4 lithium-ion battery cells. Normally, with time, cells are discharged. Does the given gate voltage by driver decrease or could it be constant? Second question of mine, as you can see in the picture, there is a typical appliction for MOSFET. However,it is said 2.7A maximum. I checked the MOSFET that are used continious drain current is 14A and I can not find any limitations for LTC1154 driver. Can you explain me please? Thank you. link is the datsheet of the LTC1154

• The 2.7A limit is set by the 0.036$\Omega$ resistor per the function of the DS pin. 100mV/0.036 = 2.7A. – rioraxe Sep 12 '16 at 0:35
