SLOS754C June 2012 – August 2016 DRV2603
The DRV2603 can operate from 2.5V to 5.2V. The DRV2603 VDD pin can be connected directly to a battery to eliminate a linear regulator or switching power supply. A small decoupling capacitor should be placed close to the DRV2603 VDD pin.
The DRV2603 has a switching output stage which pulls transient currents through the VDD pin. A 0.1 µF, low equivalent-series-resistance (ESR) decoupling capacitor of the X5R or X7R type is recommended for smooth operation of the output driver and the digital portion of the device.
