Power MOSFET Driver with Lossless Protection
General DescriptionThe LM9061isa charge-pump device which provides the
gate driveto any size external power MOSFET configureda high side driveror switch.A CMOS logic compatible
ON/OFF input controlsthe output gate drive voltage.In the state,the charge pump voltage, whichis well above the
available VCC supply,is directly appliedto the gateof the
MOSFET.A built-in 15V zener clampsthe maximum gateto
source voltageof the MOSFET. When commanded OFFa
110µA current sink dischargesthe gate capacitancesofthe
MOSFETfora gradual turn-OFF characteristicto minimize
the durationof inductive load transient voltages and further
protectthe power MOSFET.
Lossless protectionofthe power MOSFETisa key featureof
the LM9061. The voltage drop (VDS) across the power de-
viceis continually monitored and compared againstan ex-
ternally programmable threshold voltage.A small current
sensing resistorin series withthe load, which causesa loss available energy,isnot requiredforthe protection circuitry.
Should the VDS voltage, dueto excessive load current,
exceedthe threshold voltage,the outputis latched OFFina
more gradual fashion (througha10µA output current sink)
after programmable delay time interval.
Designed for the automotive application environment the
LM9061 hasa wide operating temperature rangeof −40˚Cto
+125˚C, remains operational with VCCupto 26V, and can
withstand 60V power supply transients. The LM9061is avail-
ableinan 8-pin small outline package, andan 8-pin dual
in-line package.
