Notes: 1. Here “output stage” refers to the power MOS FET driver circuits, and “signal circuitry” refers to all

other circuits on the IC. Note that this IC is not protected against reverse insertion, which can

cause breakdown of the IC between V

IN

and GND. Be careful to insert the IC correctly.

2. Noninverting input of the channel 2 error amp is connected internally to Vref.
