Motor Drivers and Controllers

Toshiba offers an extensive portfolio of motor drivers suitable for the control of brushed DC motors, brushless DC motors and stepping motors. Owing to its unique motor drive technology, Toshiba motor drivers deliver high drive efficiency. Furthermore, these are housed in small packages due to the use of a new analog process. Therefore, they help achieve stable motor control and reduce system size and power consumption.

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).

Features & Benefits

  • Low current consumption prolongs battery life.
  • (ICC = 0.6 mA (typ.) in operation mode when VM = 3.0V and Ta = 25°C; ICC = 0 µA (typ.) in standby mode when VM = 3.0V and Ta = 25°C)
  • Low on-resistance reduces IC losses generated by voltage drops in the motor driver and increases the voltage applied to the motor, contributing to improved motor torque.
  • (Ron = 0.11Ω (typ.) (total of high and low sides in large mode when VM = 5V and Ta=25°C)
  • PWM control at 500 kHz is possible by high-speed output switching characteristics (ton = 90 ns, Toff = 90 ns).

Applications

  • Motor applications driven by relatively low voltage batteries (1.8V to 7.0V), mobile devices (cameras, electric toothbrushes, printers) using 3.7V lithium-ion batteries, products for the home, such as electronic locks, smart meters, smart water washing, and toys using two 1.5V dry batteries, and devices using 5V USB power supply.

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.
