manufacturer:wolfson description: 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., cameras and disk drive head positioners). the 17531a operates from 2.0 v to 8.6 v using the internal charge pump, with independent control of each h-bridge via parallel mcu interface. the device features built-in shoot-through current protection and an undervoltage shutdown function. the 17531a has four operating modes: forward, reverse, brake, and tri-stated (high impedance). the 17531a has a low total rds(on) of 1.2 ω (max @ 25c). the 17531a efficiently drives many types of micromotors with low power dissipation owing to its low output resistance and high output slew rates. the h-bridge outputs can be independently pulse width modulated (pwmed) at up to 200 khz for speed/torque and current control. |
