LM9061

Power MOSFET Driver with Lossless Protection

General Description

Features

Built-in charge pump for gate overdrive of high side

drive applications

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

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 mA 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 ) 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

voltage, due to excessive load current,

exceed the threshold voltage, the output is latched OFF in a

more gradual fashion (through a 10 mA output current sink)

after a programmable delay time interval.

Electronic circuit breaker

Designed for the automotive application environment the

LM9061 has a wide operating temperature range of 40 C

up to 26V, and

to 125 C, remains operational with V

can withstand 60V power supply transients. The LM9061 is

available in an 8-pin small outline package, and an 8-pin

dual in-line package.
