The DRV1001 is a 10-channel relay driver ASIC. It consists of 10 individual driver channels. Each of them is capable of sinking 125 mA through a on-chip low-side switch from a high voltage (>24 V) supply.
10 low-side drivers with current limiting for self protection
Internal over-temperature detection
Serial communications for control of all drivers
