Power Stage

Power Stage
The power stages are built by an N-channel vertical power MOSFET (DMOS) with charge pump.
5.1
Output ON-State Resistance
The ON-state resistance
R
DS(ON)
depends on the supply voltage as well as the junction temperature T
j
.
Figure 4
shows the dependencies for the typical ON-state resistance. The behavior in reverse polarity is described in
Chapter 6.4
.
Figure 4
Typical ON-state resistance
A high signal (See
Chapter 8
) at the input pin causes the power DMOS to switch ON with a dedicated slope, which
is optimized in terms of EMC emission.
