LM9061, LM9061-Q1

SNOS738I –APRIL 1995–REVISED JANUARY 2017

LM9061 and LM9061-Q1 High-Side Protection Controller

1 Features

3 Description

The LM9061 family consists of charge-pump devices

•

Qualified for Automotive Applications

which provides the gate drive to an external power

MOSFET of any size configured as a high-side driver

or switch. This includes multiple parallel connected

MOSFETs for very high current applications. A

CMOS logic-compatible ON and OFF input controls

the output gate drive voltage. In the ON state, the

charge pump voltage, which is well above the

available V_CCsupply, is directly applied to the gate of

the MOSFET. A built-in 15-V 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 turnoff characteristic to minimize the

duration of inductive load transient voltages and

further protect the power MOSFET.

AEC-Q100 Qualified With the Following Results:

–

Device HBM ESD Classification Level 2

Device CDM ESD Classification Level C4B

•

Withstands 60-V Supply Transients

Overvoltage Shut-OFF With V_CC> 30 V

Lossless Overcurrent Protection Latch-OFF

–

Current Sense Resistor is Not Required

Minimizes Power Loss With High Current

Loads

•

Programmable Delay of Protection Latch-OFF

Gradual Turnoff to Minimize Inductive Load

Transient Voltages

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 circuitry. If

the V_DSvoltage, due to excessive load current,

exceeds the threshold voltage, the output is latched

OFF in a more gradual fashion (through a 10-µA

output current sink) after a programmable delay time

interval.
