MPC17531ATEV

NXP Semiconductors Document Number: MPC17531A Rev. 10.0, 7/2016 Technical Data 700 mA dual H-Bridge motor driver 17531A with 3.0 V compatible logic I/O The 17531A is a monolithic dual H-Bridge power IC ideal for portable electronic applications containing bipolar step motors and/or brush DC motors (e.g., DUAL H-BRIDGE cameras and disk drive head positioners). The 17531A operates from 2.0 to 8.6 V using the internal charge pump, with independent control of each H-Bridge, via a parallel MCU interface. The device features built-in shoot-through current protection and an undervoltage shutdown EV SUFFIX (PB-FREE) function. 98ASA10616D 20-PIN VMFP The 17531A has four operating modes: Forward, Reverse, Brake, and Tri-state (high-impedance). The 17531A has a low total R of 1.2 (max at 25 C). DS(on) The 17531A efficiently drives many types of micromotors with low power EP SUFFIX (PB-FREE) dissipation owing to its low output resistance and high output slew rates. The H- 98ASA00474D Bridge outputs can be independently pulse width modulated (PWMed) at up to 24-PIN QFN 200 kHz for speed/torque and current control. Bottom View This device is powered by SMARTMOS technology.
