Datasheet Driver IC for PPC High Performance, High Reliability 50V DC Brush Motor Driver for PPC s others BD63130AFM General Description Key Specifications BD63130AFM is one H-bridge motor driver for DC brush Power Supply Voltage Range: 8.0V to 46.2V motor. This driver can facilitate low power consumption by Rated Output Current: 3.0A direct PWM or PWM constant current control. There are Rated Output Current (Peak): 4.0A built in protection circuits in this IC. It is possible to output Operating Temperature Range: -25C to +85C an abnormal detection signal for Wired-OR that notifies Output ON-Resistance: 0.55(Typ) each protection circuit operation, which contributes to set (Total of upper and lower resistors) high reliability. Features Package W(Typ) x D(Typ)x H(Max) Single Power Supply Input (rated voltage of 50V) HSOP-M36 18.50mm x 9.90mm x 2.40mm Rated Output Current (peak): 3.0A(4.0A) Low ON-Resistance DMOS Output Forward, Reverse, Brake, Open Power Save Function External PWM Control PWM Constant Current Control (current limit function) Built-in Spike Noise Cancel Function (external noise filter is unnecessary) Driver for DC Brush Motor Built-in Logic Input Pull-down Resistor Cross-conduction Prevention Circuit Figure 1.
