Toshiba Adds New Low Power Consumption Brushed DC Motor Driver IC

February 20, 2020

TB67H451FNG

TOKYO—Toshiba Electronic Devices & Storage Corporation (“Toshiba”) has added "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. Mass production shipments start today.

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[1].

Over current detection is a safety function that prevents damage to the IC by turning off output when the output current exceeds the threshold level due to an overload or other reason. While the current “TB67H450FNG” is a latch type device, where output is turned off indefinitely until the power is recycled or the standby mode is reasserted, “TB67H451FNG” 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.

Applications

Industrial equipment, including OA equipment and banking terminals; small home appliances, including robot vacuum cleaners; battery powered devices (electronic locks and small household robots); and devices using 5V USB power supplies
