Signal Description

PWMA0-5

Output

Tri- stated

PWMA0-5— Six PWMA output pins.

ISA0-2

Input

(Schmitt)

Input

ISA0-2— These three input current status pins are used for

top/bottom pulse width correction in complementary channel

operation for PWMA.

Tri- stated

PWMB0-5— Six PWMB output pins.

ISB0-2

Input

(Schmitt)

Input

ISB0-2— These three input current status pins are used for

top/bottom pulse width correction in complementary channel

operation for PWMB.

FAULTB0-3

Input

(Schmitt)

Input

FAULTB0-3— These four Fault input pins are used for disabling

selected PWMB outputs in cases where fault conditions originate

off-chip.
