Key Features
- Package Dimensions unit: mm.
- Current linear drive 3227-HSOP24.
- Control V type amplifier.
- Separate power supply for output upper side bias circuit allows low output saturation by boosting this 15.3 4.3 power supply only (useful for 5V power supply types). 24.
- Upper side current detection technique loses loss voltage of current detection resistor. Voltage drop caused by this resistor reduces internal power dissipation of IC.
- Built-in short braking cir.
