Pin number 3 (26) 4 (25) 6 (22) Pin name VCC2 VCC3 VCC1

( ): LB11999H Equivalent circuit Unit (Resistance: Ω, capacitance: F) Pin function Source side predrive voltage supply pin.

Constant current control amplifier voltage supply pin.

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.
