Power Stage

5.1

Output On-state Resistance

The on-state resistance depends on the supply voltage as well as on the junction temperature

T

J. Figure 9 shows

this dependencies in terms of temperature and voltage for the typical on-state resistance

R

DS(ON). The behavior in

reverse polarity is described in chapter“Reverse/Inverse Current Capability” on Page 14.

Figure 9

Typical On-State Resistance,

R

DS(ON) = f(TJ), VDD = 5 V, VDD = 3V, VIN = high

A high signal at the input pin causes the power DMOS to switch ON with a dedicated slope.

To achieve a reasonable

R

DS(ON) and the specified switching speed a 5V supply is required.

Resistive Load Output Timing

Figure 10 shows the typical timing when switching a resistive load.
