I have a VERY simple circuit for a solenoid driver with external power mosfet (p channel). The driver is a DRV103u and turns the device on at 100% for a period, then PWM % after that to maintain activation. It works perfectly with the IRF4905PBF (TO220 package), but as soon as I test it with a IRF4905STRLPBF TO-263 (D2PAK), Surface Mount, it wont go to PWM and stays on full power. Datasheets show the IC's as virtually identical, so I need a solution to the problem, as I dont want to use a TO220 on an SMD PCB. I figure changing the 3k pull up will influence the behaviour, but would like a secind opinion.
