- No Longer Manufactured
- MPC17531
Dual H-Bridge, Motor Driver, 2-8.6 V, 1.4 A, 200 kHz
- This page contains information on a product that is no longer manufactured (discontinued). Specifications and information herein are available for historical reference only.
The NXP® MPC17531A is a monolithic dual H-Bridge power IC ideal for portable electronic applications containing bipolar step motors and/or brush DC-motors, such as cameras and disk drive head positioners.
- 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
- Features built-in shoot-through current protection and an undervoltage shutdown function
- Has four operating modes: Forward, Reverse, Brake, and Tri-Stated (High Impedance)
- Efficiently drives many types of micromotors with low power dissipation owing to its low output resistance and high output slew rates
