Brushed DC Motor Driver IC with wide voltage range and non-latching overcurrent detection


  • Wide operating voltage range
  • Low stand-by current
  • Overcurrent detection with auto-return
  • Small HTSSOP8 package, only 4.9 x 6.0mm

Toshiba's TB67H451FNG brushed DC Motor driver IC features automatic return after overcurrent detection. While the TB67H450FNG is a latch-type device, where output is turned off indefinitely until a power cycle or entering and leaving the standby mode, the TB67H451FNG has an auto-return function that resumes the operation without any external control. When the overcurrent condition subsides, operation returns to normal. The device is capable of operating from a wide range of input voltages, from 4.5 V to 44 V. The maximum motor drive output is 44 V at 3 A.
