Nisshinbo Micro Devices NJW4814MLE-TE1, 4, Boost Converter, Boost Converter 20mA

The New Japan Radio NJW4814 series is a dual H bridge driver with boost converter IC. It can boost the output voltage from Li ion battery and or a 5V power supply and drives a piezo device by two H bridge drivers. 48ms of internal fixed soft start function of the boost circuit sets a limit to start up current. The dual H bridge driver has independent signal inputs and a fault output function, therefore this product improves controllability from a microcomputer. The input frequency of this H bridge driver is up to 300kHz.
