Toshiba launches an integrated double H bridge bridge brush DC motor driver IC - TB67H401FTG

Overcurrent is a headache problem, which is mainly due to motor blocking generation, increases the number of components and circuit complexity. In applications where you need to monitor and feed back motor status, an IC that provides a current limit detection function is as "mirror", which is the true look of the motor operation. Recently, Toshiba launched a integrated dual H bridge with brush DC motor driver IC - TB67H401FTG, which can be used in office equipment, ATM, household appliances, sweeping robots and other applications. TB67H401FTG is like a mirror, always detecting the real state of the current, as follows: Marker output The TB67H401FTG relies on the built-in marker output circuit, providing an indication when the current reaches the upper threshold, and does not require an external circuit to achieve a smaller and efficient motor solution. Mode switch (single bridge and dual bridge mode) TB67H401FTG supports forward transfer (CW), reversal (CCW), brake (short circuit brake), stops (OFF) four drive mode, plus a mode switching function, effectively expands the application range. The single-bridge mode supports single-channel current up to 6.0A, and the dual bridge mode can use two motors, each IC drives a motor of up to 3.0A. Error detection TB67H401FTG provides superheated protection detection, overcurrent protection detection and undervoltage lock detection. Error detection signals can be output to external devices to effectively improve security. With the "mirror" of TB67H401FTG, the current state of brush DC motor is in our control. , Read the full article, original title: TB67H401FTG, "mirror" in the current state Article Source: [Micro Signal: Toshiba_Semicon, WeChat public number: Toshiba hard drive] Welcome to add attention!
