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
m
A current sink discharges the gate capacitances of
the MOSFET for a gradual turn-OFF characteristic to mini-
mize 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
DS
) across the power
device is continually monitored and compared against an
externally 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 circuit-
ry. Should the V
DS
voltage, due to excessive load current,
exceed the threshold voltage, the output is latched OFF in a
more gradual fashion (through a 10
m
A output current sink)
after a programmable delay time interval.
Designed for the automotive application environment the
LM9061 has a wide operating temperature range of
