3 Amps transient) to a
common positive power supply. The switches are fully
protected from excessive voltage, current and
temperature. An instantaneous power sensing circuit
calculates the product of the voltage across and the
current through each DMOS switch and limits the
power to a safe level. The device can be disabled to
produce a “sleep” condition reducing the supply
current to less than 10 ВµA. Separate ON/OFF control …
