... TOSHIBA Bi-CMOS Integrated Circuit Silicon Monolithic TB6549FG, TB6549PG,TB6549HQ Full-Bridge Driver IC for DC Motors The TB6549FG/PG/ full-bridge driver IC for DC motors that uses an LDMOS structure for output transistors. High-efficiency drive is possible through the use of a MOS process with low ON-resistance and a PWM drive system. Four modes, CW, CCW, short brake, and stop, can be selected using IN1 and IN2 ...

Otherwise, the current or power consumption may exceed the absolute maximum rating, and exceeding the rating(s) may cause the device breakdown, damage or deterioration, and may result injury by explosion or combustion. In addition, do not use any device that is applied the current with inserting in the wrong orientation or incorrectly even just one time. TB6549FG/PG/HQ 20 2010-07-13 ...
