HIP0063
PRELIMINARY
October 1995
Hex Low Side MOSFET Driver with Serial or Parallel Interface and Diagnostic Fault Control
Description
The HIP0063 is a logic controlled, six channel Low Side Power Driver. As shown in the Block Diagram, the outputs are controlled via the serial data interface or, by user option, each output may be independently controlled from the respective parallel input. In addition, PWM logic switching control (HLOS) may be directly applied to channels 0 and 1 in parallel, or channels 4 and 5 in parallel. Output fault conditions may be detected as an output load short to supply when the output is ON or as an open load/ground short when the output is OFF. If an over-current short exists at one output, gate drive goes to a low duty cycle mode.
