    Hi all,

    May i know what is the purpose of the capacitor and the zener diodes is used for when connecting the driver to the H-bridge? And i know i need a resistor to make sure the transistor stay off when it is suppose to. but how does that works?

    Below is the attachment of my circuit diagram.

    I don't see any Zeners. And specifically which capacitors?

    I see that this has been posted before and others see them.:confused:

    Also where is the low side bridge connection.

    Maybe some things are assumed when more experienced than I.

    You have to look at the data sheet. It's a trick question.;)

    Hi guys,

    Sorry for the lousy information i provide, and reason for repeated post is because i thought that post is being neglected. hahaz...

    The zener diode supposed to be connected in parallel with SRC_HS1 and GATE_HS1, as well as SRC_HS2 and Gate_HS2.
