Full-Bridge Driver IC for DC Motors
The TB6549F/FG/P/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) (F/FG,P/PG type) / 4.5 A (max.)
(HQ type)
• Low ON-resistance: 0.5 Ω (typ.)
• PWM control capability
• Standby system
• Function modes: CW/CCW/short brake/stop
• Built-in overcurrent protection
• Built-in thermal shutdown circuit
• Package: HSOP-20/DIP-16
