SWITCHING OPERATION

If IC exceeds ICO, where ICO =

V(ref)

the switch

cuts off the output transistors and tests the value

of current IC, with time constant 0.5 Cd.

On power up the internal start system cuts off the

output transistors until VCC reaches a value permit-

ting normal operation of the circuit.
