Functions
- Current linear drive
- Control V type amplifier
- Top side current detection technique reduces loss voltage of current detection resistor. Voltage effect of this resistor reduces internal current drain of IC.
- Built-in current limiter circuit
- Built-in reverse blocking circuit
- Hall FG output
- Built-in 1 Hall FG/3 Hall FG switching circuit
- Built-in short braking circuit
