description
The TPIC2801 octal intelligent-power switch is a monolithic BIDFET† integrated circuit designed to sink currents up to 1 A at 30 V simultaneously at each of eight driver outputs under serial input data control. Status of the individual driver outputs is available in serial data format. The driver outputs have overcurrent limiting and out-of-saturation voltage protection features. Applications include driving solenoids, relays, dc motors, lamps, and other medium-current or high-voltage loads.
The device contains an 8-bit serial-in, parallel-out shift register that feeds an 8-bit parallel latch, whic...
