Low Power Consumption Brushed DC Motor Driver Delivers up to 3.5A at 50V

February 24, 2020 by Paul Shepard

Toshiba Electronic Devices & Storage Corporation has added the TB67H451FNG to its lineup of low power consumption brushed dc motor driver ICs in the popular pin-assignment HSOP8 package. The new IC features automatic return after over current detection. Fabricated with the BiCD process, the TB67H451FNG is rated at output voltage 50V, maximum current 3.5A.

The new IC can drive brushed dc motors with a wide range of power supply, from 4.5V to 44V. The numerous applications it supports include mobile devices and devices with 5V USB power supply, and industrial devices, home appliances, printers, and banking terminals that require a high power drive of up to 3.5A.

The over current protection in the TB67H450FNG is a latch type device, where output is turned off indefinitely until the power is recycled or the standby mode is reasserted

The TB67H451FNG also has an auto return function that resumes the operation without any external control. When the over current condition subsides, operation returns to normal. More suitable type can be selected by application.

Summary of Features

  • Monolithic IC using BiCD process
  • Capable of PWM constant current drive and direct PWM drive
  • Supporting 4 operation modes, Forward / Reverse / Brake / STOP (OFF)
  • Built-in output MOSFET with Low on-resistance (High side + low side=0.6Ω(typ.))
  • Realization of high voltage and large current drive (Refer to “Absolute maximum ratings” and “Operating range”.)
  • Built-in various error detection functions (Thermal shutdown (TSD), over current detection (ISD), and Under voltage lockout(UVLO))
  • Built-in VCC regulator for the internal circuit operation.
