Hi,
The Pchannel mosfet is connected as follows:
Gate to the driver.
Drain to the Load
Source to +24V.
When the MC34152 pulls its output pin to ground, the connected gate pin will be at -24V with respect to source and mosfet is on.
When the MC34152 drives its output pin to +12V, the connected...
Thanks for looking at the schematic.
I will keep only one bottom ground plane and remove the top ground one.
I will make a clean schematic and post it here.
Regarding Q2 being permanently on, i will check up on P channel mosfet and reply back.
Hi FvM,
I typed MC34125 instead of MC34152 driver by mistake.
Regarding copper pours, I have put ground planes of solid copper on both top and bottom layer.
You have mentioned this reduces circuit inductance. I understand that it is helpful (Reduces oscillations in gate drive path?)
Am I right...
Hi,
I am making a half bridge power amplifier that operates at 24 V.
The bridge has to supply around 3A current to an inductive load (10mH)
The bridge will be controlled using 20kHz PWM from a microcontroller.
I have put a ACS712 current sensor in the load path to give feedaback to the...
