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.
Features
• Power supply voltage: 30 V (max)
• Output current: 3.5 A (max) (FG,PG type)/4.5 A (max.) (HQ
type)
• Low ON-resistance: 1.0 Ω (up + low/typ.)
• PWM control capability
• Standby system
• Function modes: CW/CCW/short brake/stop
• Built-in overcurrent protection
• Built-in thermal shutdown circuit
• Package: HSOP20/DIP16/HZIP25
The TB6549HQ is a Sn-plated product. (The Pb-containing
materials with a high melting point that are exempted from
RoHS directives are used inside the IC.)
About solderability, the following conditions were confirmed
(1)Use of Sn-37Pb solder Bath
·solder bath temperature: 230℃
·dipping time: 5 seconds
·the number of times: once
·use of R-type flux
(2)Use of Sn-3.0Ag-0.5Cu solder Bath
·solder bath temperature: 245℃
·dipping time: 5 seconds
·the number of times: once
·use of R-type flux

Note: This product has a MOS structure and is sensitive to electrostatic discharge. When handling this product,
ensure that the environment is protected against electrostatic discharge by using an earth strap, a conductive
mat and an ionizer. Ensure also that the ambient temperature and relative humidity are maintained at
reasonable levels.
