When the current limit is reached, this is signaled at an error message output which also indicates undervoltage and overtemperature. There is a safety shutdown function for the output stage in the event of overtemperature.
The device can be driven by either LVDS or TTL pulse signals.
iC-NZN and iC-NZP have a standby mode with a low current consumption of < 50 µA. The iC-NZN/NZP is in production and sold through local distribution. The price is $4.28 in 1000 pcs quantities.
