Other Parts Discussed in Thread: DRV8839,
Hi
I need to control about 8 latching solenoids and relays, therefore i have originally used 8 DRV8837, as shown in the first image below.
I would like to know would it be possible to achieve controlling all 8 solenoids/relays using only 5 Driver ICs as shown below. At any given time only one solenoids will be controlled, therefore i have common drive signal and multiple enables. So when the common driver signal is HIGH and only the appropriate other driver is enabled, it would operate solenoid. But if the other pin on driver is also HIGH but a slightly lower voltage to the COMMON drive signal, what effect would that have?
Or would the DRV8839 be better options as each output can also be set to Z if i am correct, while on DRV8837 this not possible unless both are Z?
Thank You
