This multi–mode current sensing input can be used for either source high–side, load high–side,
source–return low–side, or load low–side sensing. It is common to a Differential Amplifier, Inverting
Amplifier, and a Noninverting input path. Each of these sensing paths indirectly connect to the current
sense input of the Transconductance Amplifier. This input is connected to the high potential side of a
current sense resistor when used in source high–side, load high–side, or load low–side current
sensing modes. In source return low–side current sensing mode, this pin connects to the low potential

This pin is connected to a high impedance node within the transconductance amplifier and is made
available for loop compensation. It can also be used as an input to directly control the Drive Output.

This is the positive supply voltage for the regulation control IC. The typical operating voltage range is
power supply/battery charger output through a resistor divider. The input threshold is controlled by
Pin 6.

This is a dual function input that is used for either high–side current sensing, or as a voltage threshold
adjustment for Pin 5. This input is connected to the low potential side of a current sense resistor when
used in source high–side or load high–side current sensing modes. In all low–side current sensing
modes, Pin 6 is available as a voltage threshold adjustment for Pin 5. The threshold can be externally
adjusted over a range of 0 V to 1.2 V with respect to Pin 4, or internally fixed at 1.2 V by connecting

This is a source–only output that normally connects to a linear or switching regulator control circuit.
This output is capable of 15 mA, allowing it to directly drive an optoisolator in primary side control
