TOSHIBA Bi-CMOS Integrated Circuit Silicon Monolithic
TB6561FG
Dual Full-Bridge Driver IC for DC Motors
The TB6561FG is a dual bridge driver IC for DC brush motor that
contains MOS transistors in an output stage.
By using low ON-resistance MOS transistors and PWM current
control circuitry, the driver achieves high efficiency.
Features
• Power supply voltage: 40 V (max)
• Output current: 1.5 A (max)
• Low ON-resistance: 1.5 Ω (upper and lower transistors/typ.)
• Direct PWM current control system
• Power-saving function
• Forward/reverse/short brake/stop modes
• Over-current protection: I
LIM
= 2.5 A (typ.)
• Thermal shutdown
• Package: SSOP30-P-375-1.00

The absolute maximum ratings of a semiconductor device are a set of specified parameter values that must not be
exceeded during operation, even for an instant.
If any of these ratings are exceeded during operation, the electrical characteristics of the device may be irreparably
altered, in which case the reliability and lifetime of the device can no longer be guaranteed.
Moreover, any exceeding of the ratings during operation may cause breakdown, damage and/or degradation in other
equipment. Applications using the device should be designed so that no maximum rating will ever be exceeded under
any operating condition.
Note 1: Please use output voltage within the above absolute maximum rating, 40 V, in which includes back-EMF
voltage.
Note 2: The output current may be subject to the duty cycle, ambient temperature and heatsink. Ensure that the
junction temperature does not exceed 150 °C (max).
Note 3: When mounted on a board (50 mm × 50 mm × 1.6 mm, Cu area: 70 %)
