Description
Single-channel low-saturation voltage bidirectional motor driver

Features
• The low saturation voltage reduces IC internal heating and allows a high voltage to be applied to the motor. Thus this device can be used even in environments with a high operating ambient temperature.
Output saturation voltage: Vsat1 = 0.25 V typical (Io=0.2A)
(High side + low side): Vsat2 = 0.55 V typical (Io=0.5 A)
Operating temperature range: Ta = -30 to 85 ¡ãC

• The LB1930M features the wide operating voltage range of 2.2 to 10.8 V and the low standby current drain of 0.1 µA, and therefore can easily be used in battery operated systems.

• To minimize through currents, the LB1930M internal logic passes through an internal standby state when switched by the input signals between forward/reverse and brake, or between forward and reverse.

• There are no constraints on the supply voltage. For example, the LB1930M can be used with VCC = 3V, VIN = 5V.

• If the IC chip exceeds 180 ¡ãC due to an output short causing a large current flow, the built-in thermal protection circuit suppresses the drive current to prevent fires or destruction of the IC.

• MFP-10S miniature package. Also, the LB1930M features the high allowable power dissipation of Pd = 800 mW.
