LB1930MC
Overview
The LB1930MC is a low saturation voltage single-channel H-bridge Brush DC motor driver that supports
low-voltage drive.
Function
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 (I
O
= 0.2A)
(High side + low side): Vsat2 = 0.55V typical (I
O
= 0.5A)
Operating temperature range: Ta = -30 to +85°C
The LB1930MC features the wide operating voltage range of 2.2 to 10.8V and the low standby current drain
of 0.1A, 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 LB1930MC can be used with V
CC
= 3V, and V
IN
= 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.

800mW.
