• Low saturation voltage, typically 1.15 V (at 0.7 A)

• Soft switching drive circuit

• No need for an output snubber circuit

Functions

• 1.0 A per phase, 3-phase drive circuit (current driver)

• Digital speed control circuit

• FG Amp

• Index circuit

• Current limiter circuit

• Over-temperature shutdown circuit (OTSD)
