3 Description

The DRV81315/A-Q1 integrates single protected low side switch with a low RDS(ON) of 100mΩ. The device can be controlled by means of a GPIO interface. The switch is protected against over current by means of an internal fixed threshold current limit. The switch is protected against overtemperature by integrated overtemperature sensor. The switch integrates an output overvoltage protection for inductive load demagnetization. Faults report is available as an open drain STATUS output. The DRV81315A also supports open-load/short to GND detection diagnostic in the off state, reported on the STATUS pin. The DRV81315/A are available in 6-pin DRL(SOT-563) package and 8-pin HSOIC(DDA) thermally enhanced package (Eco-friendly: RoHS & no Sb/Br).
