The Vs pin supplies operational power to the MC33185.
This pin controls the turn OFF of output.
This pin is internally connected to the DMOS output transistor which source
current into the corresponding load. The output incorporates dynamic clamping
to accommodate inductive load. In order to reduce RFI, the output voltage and
supply current rise and fall times are limited (see Þgure below). In addition, the
output has an overcurrent detection and current limiting.
This pin controls the turn ON and turn OFF of output when reset pin is at high
level. It is a CMOS input.
This pin is the circuit ground.
