NXP Semiconductors 17531A
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 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 function.| Part No. | 17531A |
