Power Stage
The power stages are built using an N-channel vertical power MOSFET (DMOS) with charge pump.
5.1
Output ON-state Resistance
The ON-state resistance RDS(ON) depends on the supply voltage as well as the junction temperature TJ. Figure 8
shows the dependencies in terms of temperature and supply voltage for the typical ON-state resistance. The
behavior in reverse polarity is described in Chapter 6.4.

Rdson_180.vsd
A high signal at the input pin (see Chapter 8) causes the power DMOS to switch ON with a dedicated slope, which
is optimized in terms of EMC emission.
