Short Circuit in On-state
If a switch is already on and the current rises above the shutdown threshold
time
voltage
Figure 17
10.1.2
For the high-side switches, an open-load in OFF-state scheme is used as shown in
up by a current source
the voltage rises above this threshold, the open-load signal is set to high. This is equivalent to comparing the load
resistance to the value
reset or by a power-on reset.
The pull-up current can be switched on and off by the OpLxON bits. This bit should be set to LOW (i.e. pull-up
current switched off) if an output is used to drive LEDs because they may emit light if biased with the pull-up
current.
