1A/50V Octal Low Side Power Driver With Serial Bus Control and Fault Protection

The HIP0045 is a logic controlled, eight channel Octal Serial Power Low Side Driver. The serial peripheral interface (SPI) utilized by the HIP0045 is a serial synchronous bus compatible with Intersil CDP68HC05, or equivalent, microcomputers. As shown in the Block Diagram for the HIP0045, each of the open drain MOS Output Drivers have individual protection for overvoltage and over-current. Each output channel has separate output latch control with fault unlatch and diagnostic or status feedback. Under normal ON conditions, each output driver is in a low voltage, high current state of saturated turn-on.
