LB1840M

Ordering number: EN4996 Monolithic Digital IC LB1840M Low-voltage/Low-saturation Bidirectional Variable Constant-voltage Motor Driver Overview The LB1840M is a low-voltage, low-saturation, three-input type two-channel bidirectional motor driver that permits switching between constant-voltage regulated output and saturated output. The design is ideal for a two-phase bipolar driver for stepping motors. Package Dimensions unit: mm 3111-MFP14S [LB1840M] Features . Wide operating voltage range (3.0 to 9.0 V). . Low saturation voltage = 0.40 V at I = 200 mA. .V Consumes almost no current in standby mode µA or less). .
