On the DRV 595, what is the difference between these pins. Both of them indicate that they are for shutdown. The Hi-Z pin reads that is for fast disable of the outputs while the SDZ pin reads shutdown logic but its not clear what it does or if it’s a duplicate of function of the Hi-Z pin. The block diagram shows both pins as inputs to a TTL buffer and subsequentially Gain Control (pg 2). There is a snippet on reading:
START-UP/SHUTDOWN OPERATION
The DRV595 employs a shutdown mode of operation designed to reduce supply current (Icc) to the absolute minimum level during periods of non use for power conservation. The SDZ input terminal should be held high (see specification table for trip point) during normal operation when the amplifier is in use. Pulling SDZ low will put the outputs to Hi-Z and the amplifier to enter a low-current state. It is not recommended to leave SDZ unconnected, because amplifier operation would be unpredictable.
If I am looking to Enable or Disable the chip how should I use these two pins, should both be tied hi for enable and low for disable?
