High-Side Drivers - HSDRV (S12HSDRV1)
13.1
The HSDRV module provides two high-side drivers typically used to drive LED or resistive loads (typical
240 Ohm). The incandescent or halogen lamp is not considered here as a possible load.
13.1.1
The HSDRV module includes two independent high-side drivers with common high power supply. Each
driver has the following features:
