LB1930M-TLM-E Datasheet, PDF (1/5 Pages) ON Semiconductor – Bidirectional Motor Driver

Ordering number : EN6068C
LB1930M
Monolithic Digital IC
Low-Voltage, Low-Saturation
Bidirectional Motor Driver
Overview
The LB1930M is single-channel forward/reverse DC brush motor driver. This device is optimal for CD, DVD and Blue
Ray Disk player loading motors. And it is possible to use it for others as a general-purpose product.
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 = 0.25V typical (IO = 0.2A)
(High side + low side):
Vsat2 = 0.55V typical (IO = 0.5A)
Operating temperature range: Ta = -30 to +85°C
• The LB1930M features the wide operating voltage range of 2.2 to 10.8V and the low standby current drain of 0.1μA, 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 relationship between the input voltage and the supply voltage. For example, the
LB1930M can be used with VCC = 3V, and VIN = 5V.
• If the IC chip exceeds 180°C 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 = 800mW.
