6.1 Overview

The DRV81325/A -Q1 are dual channel low side switch drivers with each integrated switch of typical RDS(ON) 110mΩ. Each switch has integrated overvoltage protection for safe demagnetization of Inductive loads. The devices are powered over control pins INx per channel. Each channel is protected against over current by means of a fixed integrated current limit. Each channel further also has an overtemperature protection. Diagnostic feedback is available per channel over an open drain output STATUSx on the DRV81325A to alert the user of overtemperature condition on the Output. The DRV81325A is available in 8-pin HSOIC(DDA package) , 8-pin SOIC(D package). The DRV81325 is available in 8-pin SOIC(D package).
