7 Detailed Description

7.1 Overview

The LM9061 is a high-side controller that can protect the load from overcurrent and overvoltage. An internal

current, exceed the threshold voltage, the output is latched OFF after a programmable delay time interval.

7.3 Feature Description

7.3.1 MOSFET Gate Drive

The LM9061 contains a charge pump circuit that generates a voltage in excess of the applied supply voltage to

provide the gate drive to high-side MOSFET transistors. Any size of N-channel power MOSFET, including

multiple parallel connected MOSFETs for very high current applications, can be used to apply power to a ground

referenced load circuit in what is referred to as “high-side drive” applications. Figure 12 shows the basic

application of the LM9061.
