Datasheet 36V 2ch DC Brush Motor Driver BD60203EFV General Description Key Specifications BD60203EFV is 2ch H-bridge motor driver for DC brush Power Supply Voltage Range: 8.0 V to 28.0 V motor. This driver can facilitate low power consumption by Rated Output Current: 1.7 A PWM constant current control. Various protection circuits Rated Output Current (Peak): 3.0 A are built in. And also a circuit for lock detection is built in, Operating Temperature Range: -25 C to +85 C so it is possible to output an error detection signal Output ON-Resistance: 0.65 (Typ) corresponding to Wired-Or signaling motor lock status. It (Total of upper and lower resistors) contributes to high reliability of the set.
