I want to use this Part TBD62786 - Datasheet as High-Side switch driven by an external signal. But i don't know how to connect it properly.
My thinking is: VCC/GND are connected to the power supply (Caps etc.) The OX pins are connect to the (e.g. resistive) load which then connects to GND. The IX pins are connected via pullup to VCC, as well as to GND via NPN/NMOS driven by the external circuit. GND is common. External signal is 3V3-CMOS square-wave fed into the NPN/NMOS.
As is read the Datasheet:
- VCC<->GND must be at least 2.8V for proper ON/OFF, but IC does "survive" <2.8V besides Ix-signals beeing activated via NPN/NMOS (see above)
- VCC<->V(Ix) must not exceed 30V (So when using VCC->Pullup<->Ix<->NMOS/PNP VCC must be <30V, or V(Ix) > 20V if VCC=50V)
- Channels can be paralelled without constraint.
Thank you in advance - as i could not find any external documentation.
