Details
The LB1938FA-BH is a versatile stepper motor driver IC designed to simplify the control of bipolar stepper motors. With a maximum output current of 2.7A per channel, this IC is capable of driving two-phase motors with ease. Its simple step/direction input interface allows for seamless integration with microcontrollers and external control devices, making it ideal for a wide range of applications
Key Features
Ultraminiature Micro8 package
The low saturation voltage means that the voltage applied to the motor is higher and IC heat generation is reduced. This allows this IC to be used in environments with higher ambient operating temperatures. Output saturation voltage (high side + low side): VOsat = 0.15V typical (IO= 100mA)
The wide usable voltage range and the low standby mode current drain of 0.1 A make this IC optimal for battery operated equipment.
There are no constraints on the relationship between the inputsignal voltage and the supply voltage. For example, this IC can be use at VCC= 3V and VIN = 5V.
Thermal protection circuit limits the drive current and prevents the IC from causing a fire or being destroyed if the IC chip temperature reaches or exceeds 180C due to large currents flowing whenthe outputs are shorted due to, for example, motor layer shorting or other phenomena.
