MPC17550
features an on-board DC / DC boost converter that allows motor operation all the way down to 1.6 V (the boost converter supplies the gate-drive voltage for each of the four independent H-bridge output stages). Each output bridge has its own gate-drive and logic circuitry with built-in shoot-through current protection.
The 17550 has four operating modes: Forward, Reverse, Brake, and Tri-Stated (High Impedance). The 17550 has a low total RDS(ON) of 1.2 Ω max @ 25°C. In addition, it can be set into a very low currentdrain standby mode.
The H-Bridge outputs can be independently PWM’ed at up to 200 k Hz for speed/torque and current control. The 17550 can efficiently drive many types of micromotors owing to its low output resistance and high output slew rates.
