What the TB67H450 does
The TB67H450FNG is a PWM chopper type DC brushed motor driver featuring a monolithic BiCD process design. It supports 50 V output voltage and 3.5 A maximum current with a total on-resistance of 0.6 Ω. The device offers four operation modes including forward, reverse, brake, and stop, while integrating built-in error detection functions like thermal shutdown and overcurrent protection. It includes a VCC regulator for internal circuit operation and is available in an HSOP8 package. Engineers typically use this component to control DC brushed motors requiring precise current drive and robust protection against electrical faults or thermal stress in industrial applications.
