See also VON(CL) in table of protection functions and circuit diagram page 9. 11 ) Measured with load; for the whole device; all channels off 12 ) Add IST, if IST > 0 13 Integrated protection functions are designed to prevent IC destruction under fault conditions described in the data sheet. Fault conditions are considered as "outside" normal operating range. Protection functions are not designed for continuous repetitive operation. 14 ) If channels are connected in parallel, output clamp is usually accomplished by the channel with the lowest VON(CL) |
