LM9061
Power MOSFET Driver with Lossless Protection
General Description
The LM9061 is a charge-pump device which provides the
gate drive to any size external power MOSFET configured
as a high side driver or switch. A CMOS logic compatible
ON/OFF input controls the output gate drive voltage. In the
ON state, the charge pump voltage, which is well above the
available V
CC
supply, is directly applied to the gate of the
MOSFET. A built-in 15V zener clamps the maximum gate to
source voltage of the MOSFET. When commanded OFF a
110 μA current sink discharges the gate capacitances of the
MOSFET for a gradual turn-OFF characteristic to minimize
the duration of inductive load transient voltages and further
protect the power MOSFET.
Lossless protection of the power MOSFET is a key feature of
the LM9061. The voltage drop (V
) across the power de-
vice is continually monitored and compared against an ex-
ternally programmable threshold voltage. A small current
sensing resistor in series with the load, which causes a loss
of available energy, is not required for the protection circuitry.
Should the V
voltage, due to excessive load current,
exceed the threshold voltage, the output is latched OFF in a
more gradual fashion (through a 10 μA output current sink)
after programmable delay time interval.
Designed for the automotive application environment the
LM9061 has a wide operating temperature range of 40C to
+125C, remains operational with V
CC
up to 26V, and can
withstand 60V power supply transients. The LM9061 is avail-
able in an 8-pin small outline package, and an 8-pin dual
in-line package.
