Functional Description and Electrical Characteristics
Figure 8
Phase Synchronization Diagram
The TEST, SCI3, SCO2, SCO3, and AMUX pins are used during IC level test. These pins should be connected
directly to ground for normal device operation.
The FAULT pin is an open drain output pin. This pin will be pulled low by the device when an unmasked fault has
been detected. The fault masks are programmed via SPI message #1.
Electrical Characteristics:
V5D = 4.75V to 5.25V, Vbat = 5.5V to 42V,
T
j = -40 °C to +150 °C, all voltages with respect to ground, positive
current flowing into pin (unless otherwise specified)
