Power Stage
5 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.
5.2 Turn ON / OFF Characteristics
Figure 5 shows the typical timing when switching a resistive load.
