TI Smart High Side Switches can be used to provide power to LED modules by either directly driving LEDs or by driving LED modules. The use of multiple Smart High Side Switches in a control module to power multiple LED modules is shown in Figure 5-2.
The Smart High Side Switch in the control module serves three primary functions:
The diagnostics are especially important in modules without an MCU and where no information on the status of the lights can be obtained from the LED lighting ECUs.
