TB6549FG/PG/HQ
TOSHIBA Bi-CMOS Integrated Circuit Silicon Monolithic
TB6549FG, TB6549PG,TB6549HQ
Full-Bridge Driver IC for DC Motors
The TB6549FG/PG/HQ is a 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.
