Power Stages
The high-side power stage is built using a N-channel vertical Power MOSFET with charge pump.

Output ON-State Resistance
The ON-state resistance RDS(ON) depends mainly on junction temperature TJ. Figure 15 shows the variation of
RDS(ON) across the whole TJ range. The value “2” on the y-axis corresponds to the maximum RDS(ON) measured
at TJ = 150 °C.
