TB6549PG

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.)
