Dual H-Bridge Motor Driver

www.DataSheet4U.com Freescale Semiconductor Advance Information Document Number: MPC17533 Rev. 3.0, 7/2006 0.7 A 6.8 V Dual H-Bridge Motor Driver The 17533 is a monolithic dual H-Bridge power IC ideal for portable electronic applications containing bipolar stepper motors and/or brush DC-motors (e.g., cameras and disk drive head positioners). The 17533 operates from 2.0 V to 6.8 V, with independent control of each H-Bridge via parallel MCU interface (3.0 V- and 5.0 V-compatible logic). The device features built-in shoot-through current protection and an undervoltage shutdown function. The 17533 has four operating modes: Forward, Reverse, Brake, and Tri-Stated (High Impedance). The 17533 has a low total RDS(ON) of 1.2 Ω (max @ 25°C). The 17533’s low output resistance and high slew rates provide efficient drive for many types of micromotors.

The device features built-in shootthrough current protection and undervoltage shutdown. The 17533 has four operating modes: Forward, Reverse, Brake, and Tri-Stated (High Impedance). The MOSFETs comprising the output bridge have a total source + sink RDS(ON) ≤ 1.2 Ω. The 17533 can simultaneously drive two brush DC motors or, as shown in the simplified application diagram on page 1, one bipolar stepper motor. The drivers are designed to be PWM’ed at frequencies up to 200 kHz. FUNCTIONAL PIN DESCRIPTION LOGIC SUPPLY (VDD) The VDD pin carries the logic supply voltage and current into the logic sections of the IC. VDD has an undervoltage threshold. If the supply voltage drops below the undervoltage threshold, the output power stage switches to a tri-state condition. When the supply voltage returns to a level that is above the threshold, the power stage automatically resumes normal operatio
