產品描述
WS7140S is single channel high-side drivers with currentsense analog feedback for automotive applications, the devicesare designed to drive 12 V automotive grounded loads througha 3 W and 5 V
WS7140S integrates advanced protective functions such asload current limitation, overload active management by powerimitation and overtemperature shutdown
A dedicated multifunction multiplexed analog output pindelivers sophisticated diagnostic functions including highprecision proportional load current sense, in addition to thedetection of overload and short circuit to ground, short to Veeand OFF-state open-load.
A sense enable pin allows OFF-state diagnosis to be disabledduring the module low power mode as well as external senseresistor sharing among similar devices.
WS7140S is available in ESOP-8L package.
