The recommended operating voltage range for the SNJ55189AW is 3.3V to 5.5V, although it can tolerate up to 6V for short periods.
The thermal shutdown feature is activated when the junction temperature exceeds 150°C. To handle this, ensure proper heat sinking, reduce power consumption, or implement thermal monitoring and shutdown in your design.
The maximum current rating for the SNJ55189AW is 1A per channel, but this can be limited by the package thermal resistance and PCB design. Ensure proper thermal design and derate the current accordingly.
The enable pins (EN1 and EN2) are active-low inputs. Connect them to a logic low (GND) to enable the corresponding channel, and connect them to a logic high (VCC) to disable the channel.
The internal ESD protection diodes provide protection against electrostatic discharge (ESD) events up to ±2kV on the input and output pins. They help prevent damage to the device during handling and operation.
