TB6549F/P is a full-bridge driver IC for DC motor produced by Toshiba. The IC uses LDMOS for output transistors, which can achieve high efficient drive by MOS process with low ON-resistor and PWM drive system. Four modes such as CW, CCW, short brake, and stop can be chosen by IN1 and IN2.
The Toshiba TB6549F/P is a silicon monolithic integrated circuit designed as a full-bridge driver for DC motors. It utilizes LDMOS for its output transistors to achieve high efficiency through low ON-resistance and supports a PWM drive system. The device allows selection of four operating modes: continuous forward (CW), continuous reverse (CCW), short brake, and stop, controlled via input pins IN1 and IN2.
| Supply voltage (max) | 30 V |
|---|---|
| Output current (max) | 3.5 A |
| ON-resistance (typ.) | 0.5 Q |
| Operating temperature range | -20 to 85 °C |
| Package types | HSOP-20/DIP-16 |
The IC supports four modes: CW, CCW, short brake, and stop.
The PWM input frequency should be 100 kHz or less.
