3.1.1 Versions A and B

Samples of versions A and B of the device must be ordered separately and soldered on U1. External modifications must be made when using versions A and B of this device.

The current sense feature only applies to versions A and B of this device (in place of the FLT2 pin). The current sense function is internally implemented by a current mirror. This implementation is reflected as an external resistor between the SNS pin and GND. Connect a resistor externally to ground to translate the sense current into a voltage reading. Remove R8 and R9. Add a series resistor and capacitor to create a low pass filter to filter out noise; please see the data sheet's Application Information section for more information on this configuration.

No modifications are required for the DIAG_EN pin (in place of the EN_AUX pin) as the DIAG_EN pin is controlled in the same manner as the EN_AUX pin.
