hi all
I'm try to use p mosfet ZXMD64P03X to drive atransducer I conect drain to output on transducer and source to main input 3-3.6 volt and gate to microcontroller ouput
problem
when transducer not connect output is same as input when gate is grounded (normal)
but when load transducer volt go down to 1.6-2 volt and transducer not work and when connect direct without mosfet it work ok with 3.6 volt
I want to know reason for that drop in output although transducer current max is 20ma and that mosfet should supply more than 1A
PLEASE HELP AND ADVICE HOW TO SWITCH 3.6 VOLT WITHOUT LOSSES
