LB1666 Product details

Description

Pin Name VIN IN+ IN OUT1 OUT2 RD B1 B2 C GND Function A limiting resistor is connected across VCC and VIN to adjust the current flowing into VIN to be 6 mA to 50 mA, which generates a voltage (6.7 V) on this pin and supplies a regulated voltage to the IC system and a Hall element.

Features

and Functions . Protection against motor lock and automatic return can be with a minimum number of external parts. . provided The LB1663, LB1663M, LB1666 can be operated from . . . . . either 12 V or 24 V power supply by changing an external resistor. Possible to connect a Hall element direct to the LB1663, LB1663M, LB1666. Built-in output transistors with output current 1.5 A. Built-in rotation detect function (Drive mode: ‘‘L’’, Stop mode: ‘‘H’’) Built-in thermal shutdown With radio noise red.
