Small and Simple DC Brushed Motor Control Driver IC

 

Notes:

[1] Used to control forward and reverse rotation for DC brushed motors and stepping motors. Transistors and loads have an H-shaped configuration.

[2] The rating in the large mode and the actual motor current are limited by operating conditions such as ambient temperature and power supply voltage

[3] Resistive component when current flows. The lower resistance value achieves a lower loss in motor drives and suppresses heat generation.

TC78H653FTG

2-CH Brushed Motor Drivers or 1-Ch Stepper Motor Driver

Toshiba TC78H653FTG dual-H-bridge[1] driver ICs for DC brushed motors and stepping motors that delivers the low voltage (1.8V) and high current (4.0A)[2] essential for low voltage equipment powered by dry-cell or Li-Ion batteries, such as mobile devices, electronic products for the home and USB drives.

Early generations of low voltage motor driver devices have been H-bridge driver ICs constructed with bipolar transistors, which can achieve stable operation at low voltage.

Toshiba’s new dual-H-bridge driver IC uses Toshiba’s specialized DMOS process for low voltage drives to achieve a longer battery life with a stable low voltage operation. Improved motor torque is also realized by reducing IC losses through low on-resistance[3]. The new product is suitable for motor applications driven by relatively low voltage batteries (1.8V to 7.0V).
