Toshiba TB67H450FNG Brushed Motor Driver IC is a Pulse Width Modulation (PWM) chopper Type DC driver. This driver IC is embedded with one channel of motor output block and is fabricated with the BiCD process. This brushed motor driver is rated at output voltage 50V and a maximum current of 3.5A. The TB67H450FNG brushed driver IC features built-in output MOSFET with low on-resistance and VCC regulator for the internal circuit operation. Features also include error detection functions like Thermal Shutdown (TSD), over current detection (ISD), and Under Voltage Lockout (UVLO). Applications include industrial equipment, OA equipment and banking terminals, home appliances including robot vacuum cleaners, and battery powered devices.
