Paralleling P-MOSFETs for larger current handling

Question

I am planning to use the ltc2954cts8-2, the p-mosfet version to control a circuit. 
 
 i was thinking of paralleling 2 mosfets to drive the circuit with an increased current handling capability. 
 
 does the chip have enough gate driveability to work with 2 mosfets as we are practically just bringing the voltage to 0?

Hi was1r , 
 
 Yes, in principle, the LTC2954-2 can drive two mosfets gates in parallel but note that LTC2954CTS8‑2 EN̅ output is an open‑drain control and only meant as an enable signal, not a strong MOSFET gate driver. Since its open-drain, a pull up is typically required at the output. Too large of a pull up can slow down the turn-off of your FETs. 
 
 The LTC2954-2 only needs to pull the gate node low (asserted) and then release it (deasserted), note that the EN output is specified sinking around 500uA.
